I've been on birth control for a year now, I usually always take it at 5 o'clock everyday (occasionally I'll take it later but never more than four hours later from 5 o'clock) and I've never missed taking a pill. Also just to be safe, my boyfriend and I use condoms. We've had sex twice and the condoms didn't break, the first time we had sex was four days before my last period (got my period that month on time and it lasted five days) and the other time we had sex was two days before my period that was due on the 14th (yesterday)... My period ALWAYS comes on the Tuesday Sugar pill day so it's flipping me out that it's Wednesday and it hasn't come yet, am I pregnant? Should I be worried or am I just stressing myself out over nothing?
