Brown discharge, i was supposed to have my period by now and it didn't come. i saw a little bleeding, put in my menstrual cup and never bled again, only the discharge keeps coming back. in general, i have irregular periods. what is happening?

For the right diagnosis and treatment you will have to be examined. Pl see a Gyn.

You said "irregular periods" so this maybe just that. But if you have been sexually active, consider checking a pregnancy test--early pregnancy can cause what you described. Other causes such as recent/current illness, certain medication use/discontinue, rapid weight gain/loss, even severe stress can cause menstrual changes. Check with your doc to make sure. Good luck

If you had sex since your last period, do a home pregnancy test. If the result is negative, repeat it in 4-5 days. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. Consult this site: http://www.nichd.nih.gov/health/topics/menstruation/conditioninfo/Pages/causes.aspx
