About a month ago I was gone for a weekend, and forgot my birth control at home. I ended up missing two pills, and so I took two as soon as I got home as well as the next day. Later on, I ended up having unprotected sex near the end of the 21 pills containing hormones. My period came the next day, which was early (but expected since I had missed a couple pills in the first three weeks). I know that it isn't unheard of to get your period while you're pregnant, and I was wondering what my chances of being pregnant are.
