Is Your Menstrual Cycle Normal? What You Should Know

Once you go through puberty and begin getting your period, you will have regular 
menstrual cycles that occurs about once a month. This is to help prepare your uterus 
and body for pregnancy, which causes your sex hormones to rise and fall during each 
cycle. If you don’t become pregnant, the cycles will then repeat the next month. 

Having an abnormal menstrual cycle is very common, but might be something you need 
to bring up with your doctor. Here are some signs that indicate a normal or abnormal 
menstrual cycle.


What is Considered a Normal Menstrual Cycle?

First of all, you might have a normal menstrual cycle even if it seems a little abnormal to 
you, or if it changes during certain months. Not every woman has the perfect 28-day 
cycle with ovulation on day 14. This is just an average for what a “normal” menstrual 
cycle can be.

So, what makes up a normal cycle? Here are a few things to think about:

Do you have your period most months? It is completely normal to occasionally skip a 
period from stress or external factors, but if the majority of the time, you have your 
period every month, it is usually normal.

Is your menstrual cycle between 28 and 35 days? You don’t need a menstrual cycle 
of 28 or 30 days every month, but within this range is usually considered normal. It is 
when your menstrual cycle is extremely short (20 days or less) or extremely long (40 
days or more) when it might be a concern.

Do you show signs of ovulation most months? Ovulation might show in signs like 
mid-cycle cramping or spotting, breast tenderness, or hormonal changes. If you get a 
period every month and show one of these signs, you are probably ovulating normally.

Is your period flow consistent month to month? Your period flow during your period 
is going to range from light to medium to heavy, but if it mostly follows the same pattern 
every month, it is considered normal.


Signs it Might Not Be Normal

There are quite a few signs that could mean your menstrual cycle is not normal, and 
you might have something else going on. 

You haven’t had a period in 2-3 months or longer. Skipping a period isn’t always 
cause for concern, but if it’s been 90 days or longer since a period and you aren’t 
pregnant, you should consult your doctor.

Your period or menstrual cycle varies each month. Do you notice that nothing 
seems consistent with your menstrual cycle or period? From PMS symptoms to 
bleeding, to how long your periods last, if they aren’t consistent, there could be 
something else going on.


You have intense cramping or bleeding throughout the month. In addition, if you 
have pain and spotting or bleeding throughout the month, even if it’s not every day of 
the month, it might be a sign of endometriosis, PCOS, or fibroids.
