So im 19 years old. The 2 of june 2013 I had unprotected sex with my boyfriend. It lasted 2 and a half hours with on and off breaks. Now he didnt come. Well at least he said he didn't come. But im freaking out that he may have or he might of pre come. I was due for my lady's (periods) on the 5th of june. But they came on the 15. Lasted 5 days when mine usually last longer then most girls because I have pollycystic ovaries. It was not heavy at all and mine usually are massively heavy. It was mild and then light. Since then I have not had my periods. I took a pregnancy test around a week and a half ago. It was posertive and tthen to double check I took 2 more. They both came out negative. So I had one posertive and 2 negative. I havent done another one as of yet. Im waiting to do a blood test. but I do have sore breasts. I have no sickness. Just dizziness and feel sick. I also have been getting period like pains but nothing. What do you guys think?. I would appreciate it if you guys didnt hate on me at all for my age. I am mature and realized I should have made my boyfriend cover his lover to avoid this situation. thanks ♡
