Can I be pregnant if I've been on birth control since I was 15 (I'm 24 now and married but we are waiting to have kids) and this month I missed one week of my birth control because the prescription was messed up. We made love on the second day of my ovulation. And for the past week my breasts have been really sore (I mean way more than Before my period sore). Does breast tenderness happen that early in a pregnancy or am I just getting sore because my period should be starting in 12 days? Ugh the waiting game.
