So, when I finished my period. I had unprotected sexual intercourse with my boyfriend, straight after the next day, I took the plan B method which was the morning after pill. However the next day, I had unprotected sexual intercourse again with my boyfriend and he did ejaculate inside me but I did not take another morning after pill, after having the intercourse the 2nd time round. Now, 5 days later from having the intercourse, I have started my period? It's not heavy, and it's a weird browny colour. My question is, is this early period due to taking the pill or is a sign of pregnancy? Please help. So confused.
