This is the second time I bleed after having sex with my new guy and I'm starting to get scared. At first i thought it could've been because i hadn't had sex in a while but now I'm starting to get nervous.. Should i seek medical help??? And could it be something serious, i am really worried now. Actually the first time I ended up getting my period a couple days after but this time I don't know what it could be, I'm also feeling cramps. please help :-(
