I'm on BC and have been for a couple months now. ( I dont know if this is important or not) but in March I missed basically the whole pack. In April I missed a good 4 or more. My boyfriend and I have unprotected sex a lot.. I know he came in me probably 3-4 times. Twice when it was my fertile week. Well, nine days before my expected period, I got brown discharge. This went on for 4 days. It was very light and I usually would only 'bleed' in the morning then it stops. I've been experiencing extreme fatigue, frequent urination, and I get nauseous at random times. Could this be early signs of pregnancy? Or was it my period?? Someone please help as soon as possible.
