So my period is 2 weeks late. I also had unprotected sex 2 weeks ago and I also just started birth control 2 weeks ago. I didn’t realize that it takes 7 days for birth control to be in effect without a period. My period was supposed to come the day after I had sex and it didn’t come. I took the pill when my period was supposed to come. For the past week haven’t really had any symptoms until now. Slight headaches, increased appetite even after I just ate, I’m just never full😂. Slight cramps but nothing serious like period cramps. Fatigue, backaches, and a little nausea when I eat alot. I just went to the bathroom and when I wiped I saw brown discharge. Not alot, very thin on the tissue. I also some on my underwear but not even a hint of red or pink. Can someone help me. Is what I’m experiencing part of birth control or could it be linked to early pregnancy???
