I had sex with my boyfriend unprotected on Tuesday August 3rd. I admit that he came inside of me just a bit before he was able to pull out. On Saturday August 7th i recieved my period like I was suppose to and it lasted for its usual 5 days and I thought nothing more of it. But today over a week after the end of my period I had sex again and about an hour later i used the bathroom and realized I was bleeding. While having sex i know my boyfriend didnt cut me a little or tear anything because I know what that feel like and I also read that in the early stages of pregnancy there could be a light flow of blood involved especially afte having sex. But i do not if I could have my period, be spotting a week later and be pregnant. So what do yu think? Could I be pregnant?
