If you're a woman you've been there - staring at the calendar, counting the days, doing the math, pretty sure something isn't quite adding up. It's your period, it's late, and omg, why?

WHY IS YOUR PERIOD LATE?

ARE YOU PREGNANT?!

ARE YOU SICK?

ARE YOU PREGNANT?!

ARE YOU DYING?!

YOU ARE PREGNANT

Except you're not. After taking at least seven pregnancy tests (but probably more) you're pretty sure you're not. So now what?! Why is your period late if you're not pregnant?

You Ovulated Late

Ovulating late is the most obvious and common reason that periods are a few days behind schedule. Contrary to period calculators and cycle predictors, periods don't follow an exact rhythm, however it all centers around when you've ovulated. If you ovulated on a later schedule this month than you have in the past then your period will appear late when really it's right on time according to your late ovulation. Unless you're tracking your ovulation through a reliable method (like tracking your basal body temperature or utilizing ovulation kits) then you don't really know the exact day when you ovulated, thus making predicting the exact start of your menstrual cycle a bit tricky!

If your body doesn't release eggs it doesn't ovulate and if it doesn't ovulate, you're not going to get a period.

You Didn't Ovulate at All

For some of us, our cycle is like clockwork every single month then all of the sudden, bam, late period. Sometimes the cause of a late period isn't pregnancy or even delayed ovulation, rather that you haven't ovulated at all. So why would you just not ovulate? From a hormone imbalance to polycystic ovary system (PCOS) there's actually a lot of different reasons you might not ovulate one month or that you may stop ovulating for a few months straight like...

You Have Recently Changed Your Exercise Habits

So maybe you're a couch potato who just started training for a marathon (no judgement and congrats on the marathon ambitions), or your mom just bought you your first FitBit and you're absolutely annihilating your sister-in-law in the Daily Step Challenges. Awesome, right?!

Yes! Except for that whole evolution thing. When you exert your body beyond it's usual efforts then that primal, ancestral instinct that was long-forgotten generations upon generations ago sometimes rears it's ugly head and says "Wow, you're running a lot, maybe you're being chased by bears all of the time. The last thing we're going to do here is let you grow a baby because that's going to require a lot of fat and rest, something you don't really have room in your life for, because you are running from bears almost constantly. Surely if you become pregnant you will die and so will your twenty other children whom you care for and then a third of earth's total population will cease, so yeah, we're just gonna put that ovulation on hold."

Damn, your body is really smart.

But since hopefully you're not actually being chased by bears every day like your great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great, great grandma once was go ahead and put your feet up, enjoy a little Netflix and a pint of Chunky Monkey and give your bod a chance to catch up to current day issues - like ovulating so you can start your period.

You're Not Eating Enough

All of my friends are on a diet. Some of them just eat particular fruits while others eat all of the meat. If you're on a diet that works for you, cool, but if it's caused you to lose an excessive amount of weight (around eight pounds a month is a healthy loss goal, anything more than that can be considered excessive) recently then it's possible that OMG BEARS! Your body is going to think the bears are after you, that maybe you've been running from bears too much and there aren't enough berries in the forest and you are going to die of starvation because why else would you suddenly be dropping so.much.wight? According to evolution, a starving woman is no place to home a fetus so that ovulation gets axed.

See? Are you starting to see how this whole late period thing works now?

Your Body is Nearing Menopause

The first time I got my period, I cried in the bathroom of a pizza parlor. I was 12 and way too young for this shit.

You're probably feeling the same way about menopause. Here's the thing though, evolution. I should have just named this article Evolution: Why Your Period is Such a Sneaky Sneak.

But it's the truth, life was a lot shorter back in the stone age (or whenever) and peeps were having babies real young and dying by thirty. This is probably why perimenopause, the brief stage before actual menopause, can begin as early as a woman's 30's or 40's. If you made it that long way back when, you were definitely not in a position to be having more kids, especially after decades of running from bears. If you're in your 30's or 40's and experiencing late or missed periods along with symptoms like hot flashes, low sex drive, and fatigue you may be entering the early stages of menopause.

You Are or Have Recently Been Sick

Did you have the sniffles last week? Are you in the throes of a wretched stomach virus? Catching the latest illness-of-the-week won't just put you out of work and leave you with a pile of backed up laundry and dishes, getting sick can also be a signal to your body that you're not well enough to reproduce (and I mean, that's probably true, no one wants to baby dance when they have diarrhea), delaying your ovulation which can cause your period to be seriously late, maybe even by a whole cycle. So if you're two weeks late for your period and still pulling stark white BFNs on those pregnancy tests take a deep breath, guzzle some water and get your health back in business so your body can get on track to returning to it's regularly scheduled ovulation.

Everything from illness to anxiety can prolong the start of your period. *Deep sigh*

You're Stressed

Back to that evolution thing, your body is really scared of bringing a baby into the picture when you can barely handle that bear that has come to kill you and your whole family. Because seriously, how are you going to simultaneously grow a fetus while fending off a predator with only a few scarce berries in your stomach?

But now the bear is a late mortgage payment or a failed college class or your parent's divorce (or your divorce) and your period is MIA which is stressing you out even more.

No period = no ovulation = no baby growing = maybe you will have the energy to survive this bear fight and continue to carry on human existence for another generation.

THANKS EVOLUTION.

If you think your period is late due to stress it's time to take a hard look at your circumstance and make a plan of attack for how to deal with the bears in your life so you can be chill enough to get your cycle and your life back on track.

Stressing about your late period could be why your period is late. Conundrum, am I right?

You're Dealing with a Treatable Medical Condition

In some cases, a missed period could be a sign of a medical condition like a thyroid disorder, a non-cancerous tumor, or even scar tissue from a previous procedure, all of which require medical diagnosis to treat.

You're Working a New Shift

By now you're probably like, "okay, wow, what CAN'T affect my period."

Which brings us to: Taking on a new shift at work can totally cause your period to be late.

Simply put, our circadian rhythm controls a whole slew of other biological rhythms (like ovulation) and if you're taking on a new shift at work, or your shifts are constantly changing, you're probably not getting regular sleep or sticking to a solid bedtime with can interrupt your circadian rhythm. Messed up circadian rhythm can = messed up menstrual cycle.

Your Medication

Many medications, from birth control to anti-psychotics can cause missed periods. If you're taking any meds, read up on the side effects to find out if late or missed periods are one of them.

You Are Breastfeeding

I'm going to blame this one on evolution too, since in the way back when, it would have been hard to find enough food to eat to produce breast milk and nourish a growing fetus (two things that make you pretty darn hungry) at the same time. So if you're one of the lucky ones who haven't had a period since you started breastfeeding then chances are it's as simple as that - you're breastfeeding. The hormones that tell your body to make milk also tell your body to quit making things cozy for a new baby, so you stop ovulating for a while.

Or you're like me and you're celebrating your baby's first birthday while cookin' another bean and trying not to puke all over the birthday girl's cupcakes.


¯\_(ツ)_/¯


So fun.

You can basically blame like 95% (not a scientific number) of your period problems on bears.

When to Call Your Doctor

Some sites will say to call your doctor when you're almost dead. But I say, call your doctor when you feel like it. If you're late for or skip one period and have no other obvious symptoms you're probably good to wait and see what happens next month, but if you're really concerned or just curious, call 'em up and have a chat about what concerns you should look out for and what constitutes a visit to the office.

Apps That Track Your Period

If you want to get an idea of when you can expect your period to arrive you should definitely be using one of these apps to track your cycle and receive notifications on when you're coming up to your fertile window, when you should be starting your period, and when you're officially late. Plus, these apps take data from all of your past cycles to help determine things like what symptoms are typical for you on certain days of your cycle along with helpful tips for making your period symptoms as bear-able as possible.

Tools to Track Your Ovulation

One of the smartest ways to track your period is to know when exactly you've ovulated. If you've ever leafed through your mom's copy of Taking Charge of Your Fertility or browsed BabyCenter at all then you already know that the best way to track your ovulation is by monitoring your basal body temperature with a BBT thermometer or through at-home ovulation tests. A few options to track your ovulation include:

  • A digital BBT thermometer. With this tool you can manually track your basal body temperature throughout your cycle to know on which day you ovulate.
  • A bluetooth BBT thermometer. Instead of manually recording your BBT with a digital thermometer, a bluetooth BBT thermometer and app does the work for you, all you have to do is remember to take your temp. Without much effort you'll know exactly when you're about to ovulate each month, giving you a solid idea of when to expect your period.
  • At home ovulation test kits. These are a lot like pregnancy tests, only instead of telling you if you're pregnant, these tests tell you if you're ovulating without all of the extra effort of tracking your temperature.
