Suggest Remedy For Pain In Vagina After Sex

I am 4 months pregnant and me and my boyfriend have sex at lest once a week. Well this past week during sex my vagina feels raw and it hurts, then after sex I go pee and the pee feels hot. And where he inserts his penis itchies a little when I pee. So through the rest of the day my vagina hurts and feels like he is still in me, then when I wake up the next day it still hurts but not as bad..... So wat do u think?
