I am 18 years old. I had sex january 13th. We used a condom but it broke. He came outside of me but about 10 hours later I took plan b just to be safe. January 21st, I had a early, normal 7 day period. I was due to have my next period the 20th. We haven't had sex since then because we are waiting till im on birth control. I'm just curious what are the chances i'm pregnant. We used a condom/ he pulled out/ and I used plan b. I'm being put on birth control but have to wait until my next period to start taking it and it hasn't come yet. I have a sore throat and I'm a tiny bit nauseous. im only a day late and I may be overthinking this but I would like someone to ease my nerves.
