I was on Femcon birthcontrol for over a month. It was to try to regulate my period but instead I had my period for almost a month. So I stopped taking it 4 days before thanksgiving and my period stopped on Thanksgiving day. I had sex two weeks after. I was supposed to get my next period on December 24 but didn't. Then Jan 4th I spotted pinkinsh watery discharge followed by brown discharge. No period. It was only when I wiped. I am irregular on my period but I dont have any changes in my body except that I can't sleep on my stomache like I use to and I have a small pain in my lower back, Could I be pregnant?
