Hi, I am on BCP for only 3 months , I stop my BCP in the middle of the pack, my husband and I planning having a little one. I read that it will mess up my period but I don't have an idea about that because that is my first time taking pills. After i stop taking BCP , 8 days before my expected period I experience heavy bleeding and cramps for 1 day and the next day I have a brown discharge for like 2 to 3 days. And now I am almost 17 days late, and have a white discharge.
Also experience headache , feel sick , back pain and my nipples hurt.. I have unprotected sex few times since i stop BCP..
All the symptoms you describe could easily be symptoms of PMS or from coming off the pill. You weren't on the pill for very long, so your body was just getting used to being on it - then you stop it. That really messes your body around, and so missing periods and all these symptoms are a reaction to that.
Take a pregnancy test, just to rule it out, but I think it's most likely due to coming off the pill.
