ok i had sex for the first time 4 days ago with a boy who has had sex with 5 previous partners i bled for a day after but it wasnt much and had some cramp like symptoms but the sex was unprotected as it was a heat of the moment thing anyway i took the morning after pill but i dont know whether i should go to a sexual health clinic to get checked when i have no symptoms of anything i also am worried about hiv and how likely is it tht i could get it thanks
