Help??

Holly • Hi! I`m 21 years young! School full time, while I work part time. I have the most amazing boyfriend in the world, we are like each others best friends and couldn`t be any more happier! ♡
Hey! So I need advice, so my boyfriend and I have been having a lot of unsafe sex, and now the past week I've been constipated (tmi sorry) and a lot of unusual discharge, I can't sleep at night and now I'm waking up nauseated, and can't get comfortable while sleeping and lots of dizziness, any advice? Please!!
