9 things you didn’t know about your period (but probably should).

Thanks to our brand partner, Metagenics

Periods, reds, lady days or Aunt Flo's visit — no matter what you call them, many of us experience them.

Yes, it's that time of the month that shows up uninvited, refuses to leave on time and brings with it all sorts of fun surprises.

But from unexpected symptoms to surprising facts about how our bodies work, there's a lot to uncover about menstruation.

Here are nine things you may not know about periods…

1. PMS is more than just mood swings.

Ever find yourself staring at your computer trying to send an email for an hour, but losing focus? Or suddenly everyone — including the lovely coffee guy who literally fills your cup every day — seems so annoying? That's PMS (or it can be a small part of it at least).

Premenstrual syndrome (PMS) is a group of physical and emotional symptoms that start one to two weeks before your period. And while the exact cause isn't fully understood, hormone fluctuations and levels are believed to play a key role.

Every woman may experience PMS differently as symptoms can range from mild to severe. And while mood swings can be one symptom, others include joint pain, bloating, trouble concentrating and crying spells.

Produced by Metagenics — a high-quality vitamin brand focused on supporting women's health — PMS Ease is one option designed to help relieve symptoms of premenstrual tension such as irritability, mood swings, tiredness and breast tenderness.

Formulated with vitex agnus-castus and vitamin B6, along with iodine, zinc and vitamin E, this supplement helps regulate the menstrual cycle and maintain healthy hormonal balance.

2. Feeling hot, hot, hot.

Did you know your body temperature fluctuates throughout your cycle?

Right before your period, your basal body temperature (the temperature of your body at rest) drops a little. But during ovulation, it shoots up by about half a degree all thanks to a surge in progesterone. 

So, if you've ever felt suddenly warmer or more flushed at different points in the month, now you know why.

3. Period poops are a thing.

Does your digestive system seem to have a mind of its own when your period arrives? 

That's because your body releases prostaglandins, which help your uterus contract and shed its lining. 

But prostaglandins don't just target your uterus — they can also affect your intestines, leading to loose stools or more frequent trips to the bathroom.

4. Periods might make you more sensitive to pain.

You may want to hold off on your full leg wax or getting that tattoo you've always wanted. 

Thanks to hormonal shifts — especially that estrogen dip — your pain threshold takes a nosedive. This can make cramps, headaches and even tiny injuries feel a lot more intense. 

5. Your voice could change.

Hormonal shifts can cause subtle changes in vocal cord vibration, making your voice sound slightly different (and smoother) during your period. 

So it's the perfect time to start a podcast, narrate an audiobook, deliver a speech in public or maybe just revel in your lush new vocal tones. 

6. You may crave more junk food.

Anyone else head straight for the junk food cupboard?

The body's demand for energy increases in the luteal phase (before your period) which can trigger cravings — especially for carbohydrates and sugary foods that provide quick energy.

7. Exercise might reduce cramps.

While it might be the last thing you feel like doing, light exercise (think walking or yoga) can help reduce period discomfort by increasing blood flow and releasing endorphins.

8. Your immune system could take a hit.

Do you find yourself feeling run down or catching a cold right before your period? 

Some research suggests hormonal fluctuations may influence immune responses, which could explain why some people feel run down before their period or experience flu-like symptoms before their period starts.

9. Periods may affect your sense of smell.

Ever noticed that your sense of smell is supercharged right before your period? If you can sniff out bacon from a mile away, you're not imagining it! 

During ovulation, just before your period begins, your sense of smell becomes more sensitive.

While some scientists believe this is nature's way of helping women detect pheromones, we can also just add it to the list of amazing female superpowers.
