Hello, I am currently on the Alesse contraceptive. I missed a pill one day this week, which is my first week, but I'm not sure which day. The only reason I realized it was because I looked closely at my pill pack today and realized I'm on the wrong day. I know for a fact I took my pill last night like usual. I took a pill just now because I realized that I missed one sometime this week. I also had unprotected sex the day before I started the pack. What are the chances I am pregnant?
