My boyfriend and I had sex on March 17th and he cumd in me as soon as he told me i went to the restroom and peed I thought that would get it out but fifteen minutes later I peed again and i still saw cum coming out. I got my period on the 23rd and it usually lasts about 6 days this time it lasted 4 . Its been two weeks since that happened now I've been getting really bad headaches and I've been feeling hungry every hour now I've never been this hungry so often and really emotional too. I just want to know if you can still get your period the next week after sexual intercourse. I took a pregnancy test today the 31st it came out negative and my next period will be on the 21st. Can I still be pregnant ?
