My period was on Oct. 17, 2014 and ended on 22. my bf and I had sex on Nov. 5, he use condom and he ejaculated but we just kept going for a while. I noticed the base of the condom would roll up every now and then but he just rolled it back down. I'm worried that some of the semen may have leaked down and into me. After 19 hours of the deed i took 4tablets of Nordette, and 4 on next 12hours. After that, I got headache, stomach cramps, pain in both breast, these side effects lasts until now, and it's already 1 week since I took Nordette and still no bleeding happen. I'm really worried about this. Do u think I'm pregnant or not? Answers please
