Having a pregnancy scare... I am on the birth control pills. I had been taking antibiotics for strep throat (10 day dose), finished the antibiotics and started my new pack of birth control. On the 6th night i forgot to take it, yet took it the next morning. The 7th night I had sex with a condom just incase, but it fell off unnoticed. My boyfriend came in me a little. This happened April 13, 2017. Its been 11 days (today is the 24th). It's too soon to take a pregnancy test, but my period is expected next monday. (May 1) as of now i have sore nipples and light cramping near my ovaries, sometimes shooting through lightly to my back. Chances of pregnancy?
