PLEASE HELP ASAP. I've been on the pill for about 2 years now. I started using it to help my acne and I've just continued taking it. I used to take the pill at the same time everyday until my dermatologist told me it doesn't matter as much because I'm not using it for the actual reason of birth control-to not get pregnant. The past 2-3 months I've been more irregular on the times I've taken the pill during the day. My boyfriend ejaculated but he had his boxers on. It dried after about 5- 10 minutes then I got on top of him but didn't go down very far. What are the chances I'm pregnant? Does seamen dry/not work when it comes in contact with oxygen? Thanks.
