Your period may vary from month to month, but if you're beginning to notice some differences, it could be a health issue that should be brought up to your gynecologist. It may be something that could worsen further. Read on for signs that your period isn't normal.

1. No Period At All

If you don't have a period at all, the first concern should be that you could be pregnant. A pregnancy test should be taken to rule out this possibility. You can have a blood test taken at your gynecologist's office to be sure, as a store-bought pregnancy test can sometimes give you a false negative. 

If you aren't pregnant, your stress levels may be to blame. Excess stress can cause issues with your hormones and can leave you without a period. The same goes if you've lost a considerable amount of weight. Low body mass can cause a loss of your period, as can excessive exercise. This type of period loss is called amenorrhea. 

Menopause may also be a factor in not having a period. If you're over the age of 40, you may be experiencing symptoms of menopause. A test from your gynecologist can tell if you are going through menopause.

If you've been without a period for several months (and pregnancy is ruled out), your gynecologist may put you on birth control pills to help regulate your hormones and start your period again.

2. A Lot Of Blood Clots

A heavy amount of blood clots when you have your period could be an issue with your uterine lining and it is not shedding properly. You should experience some clots, but if they are excessively large (larger than a quarter), or are having them often, it could be a few different things, miscarriage, endometriosis, fibroids, or even tumors. Tests can be run by your gynecologist if you are experiencing this issue. Don't ignore these clots.

3. A Longer Than Normal Period

Most periods last 7 days, sometimes it can be light or it could be heavy, but if it's going over those 7 days and lasting much longer than normal, it could be a thyroid issue or even an iron deficiency. If you are having periods lasting over 10 days, visit your gynecologist to have tests ran.

Your period may change every now and then, but if the changes are very noticeable and you have concerns, talk to your gynecologist about them to rule out any medical conditions. Visit a site like http://www.billingsclinic.com for more information.
