Menstruation & Your Cycle

3 Common Menstrual Cycle Questions

When it comes to your period, there are a few things you should know about your menstrual cycle — like how often you have your period and what can affect it. Whether you’ve had your period already, or you’re wondering what to expect, here are three common questions about your menstrual cycle.

1. How often will I have my period?

Your period, on average, occurs every 28 days, from the first day of your period to the first day of your next period. This can vary from 20–35 days and still be normal.

It is a good idea to keep track of your period. To do this, just circle the days you menstruate on a calendar — or use our helpful period calculator. Do this every time you get your period. After a few periods, you’ll see a pattern forming, so you’ll know how long each of your cycles will be, how long your period lasts and when it will come again. If you are worried that your period may start unexpectedly, try wearing an Always pantiliner for reassurance.

2. Why do some girls have irregular periods?

When you first start your period cycle, it might be irregular. You could have one period and then wait six months for the next one! This isn’t unusual. Until your body adjusts to your cycle, your period may be unpredictable. But after that, it should regulate itself. If not, see your doctor.

Once your period is regular, you could still have cycle changes caused by hormones. Also stress, emotions, sudden life-style change and even some medications could affect your period. Some women have noticed losing weight also alters your period.

3. Does what I eat affect my menstrual cycle?

Nutrition is necessary for growth and general good health, so the better balanced and healthier your diet, the better you’ll feel. Just before your period, you may want to avoid caffeine, salt and carbonated drinks — especially diet sodas. Some women find that these foods contribute more to uncomfortable premenstrual symptoms.

I think I just had my first period ? I know your first period can be very light, that's how mine is! It ranges from light pink, to dark brown,to pure red. I've been having cramps Bach aches and if you touch my twislers I will cut your fingers off then shove them down your throat ^^ -_- is this spotting or first period? {it soaks though a panty linnet but does nothing on a pad!

@buggylou862 that is not ok to not have it every month or two. Maybe it wasn't your period so be sure to get ready for it! If it was for sure your period then you should talk to your doctor about it.

I used to be very regular, like for two years every month. I never skipped. Now I skip every other month. I guess it is because of stress. But I hate how your first thought is always if your pregnant or not. Even if you hadn't had sex. Well that always happens to me. Does anyone else yell eff you at the people on TV that say "have a happy period" I really hate those people.
