I m an 18 year old female and I had sex for the first time 3 days ago and we didn t use a condom and I took the morning after pill the next day. I hated the experience, but now I have a funny, ugly, fishy smell around my vagina and I have an itch. I used to have an inchiness problem before so I m not sure about that. I don t know if its just paranoia, but I can t sleep and I feel dirty, what could be the problem?
