sex and pills

9 days ago I had sex with my boyfriend with a condom and when he was about to ejaculate he pulled out and when he pulled out there was stuff coming on his finger while he was taking it off the condom from the top it looked like some fluid I dont know if it was his sperm or my fluid. On the day we had sex I was ovulating and my percentage was 22% high according to eve yesterday me and him had unprotected sex and we went 2 rounds and he pulled out twice didn't cum inside me at all! I then went to the pharmacy with him and took the plan b pill yesterday. I'm supposed to get my period in 4 days ! I'm really scared that I might miss it because I might be pregnant from the time we used the condom and when he pulled out white and watery stuff was going all over his hands while taking off the condom. But 9 days ago tho before we had sex my boobs were getting a little bigger and I was having headaches and now my boobs are very big and feel hard and it almost kind of hurts to touch them they feel sore . I've been having lower abdomen cramps a little for and when I walk I get a little of shooting pain or little cramps . I don't know if thats because I'm pregnant or because I'm getting my period in 4 days! I also took a pregnancy test 9 days ago on the same day before we had sex because I was having cramps and stuff and just wanted to make sure that everything was okay and it said I wasn't pregnant and then we decided to have sex! Help?!
