Why did that happen after sex??

My boyfriend just got out of jail he has been in there for almost 2years...I wasnt suppose to start my period until today well last saturday I went to my boyfriends house and we had sex without a condom 3 times...and then I went to the restroom and there...

was blood on the toliet paper I whiped on and I thought that he just stretched me or something well later I started cramping like I was on my period so I went and checked and I was on my period...but I wasnt suppose to start that soon and my periods are usually right on time...Do you think I could be pregnant? Why did I start my period right after having sex??? Is that bad? And a lot of people told me I have a higher chance of getting pregnant cuz he hasnt had sex in a while...Im not sure I need help!!!

him not having sex in awhile doesnt make u pregnant... i had gotten mine 2 weeks early when i messed up my birth control if your on birth control that could be a possibility.. that or he might have hit some organs in there take a pregnancy test and u might want to get checked for STDs bc that too could be a possibility, stressing out can make it worse so stay calm and let your body run its course

Well I know he doesnt have any stds cuz he got checked right after he got out of prison...im going to get put on birth control next week so im going to have them check and see if im pregnant first before I get on it...When your pregnant when do you start having symtoms??
