I've been on the pill for about 3 months since I stopped breastfeeding. Everything has been as normal, until yesterday, I'm not due for my period for another week but have had some brown discharge, like the start or end of my period. So far I've had nothing today but feel like I've been hit by a truck. I have taken every pill this month and always within about an hour of my normal time so there are no issues with skipped pills. Before I was pregnant, I was on the pill for years and didn't have any issues. I guess my concern is always pregnancy, but I've been so consistent with taking it and having had antibiotics or anything that I think would cause it not to work. Any thoughts?
