I have been irregular, period wise, ever since I got it at 14. My doctor blames it on endometriosis. So a few years back he put me on the pill with Agestin and I didn't have a period the entire time (oh it was blissful :) ). A few months back my husband and I decided it was time to start trying for a baby. I went to the doctor and got off my meds. It has been 3 months and it seems like I am constantly bleeding each week. I thought by now it would be somewhat regular but I will spot one week, period the next week, off for a few days, and more spotting.
