I've been on birth control for about a year for acne and also have been on bactrim a little while. I missed a few BC pills last month and started a new pack this past week. On Friday I had sex and my bf used a condom too. He said the condom didn't leak it break but I don't know. I'm just worried about it and need some help. Could I be preggo? My times vary when I take the pill. I normally take it about 11ish pm whenever I go to sleep and that Friday when I had sex it was later at about 2am. Was I protected with the BC pill? It was a new pack and I had taken all of the pills that first week.
