I'm into my second week of my third pack of Tri-Sprintec. I haven't missed any pills and have always taken them around 9pm we every day, sometimes an hour before or up to two hours later. At the end of my second pack, I had sex for the first time and since then almost every day. About 75% of the time we use condoms also, but sometimes we don't but he always pulls out. What are my chances of pregnancy?
