Just a couple of questions for you sorry hun but the same happened to me just not at a night club
1st.. Did you report the rape?
2nd.. Did you go to the hospital for cultures and a pap??
3d. Have you seen a doc.???
I know right now you probally dont feel comfortable around anyone or anyone touching you, but please make sure you seek medical attention. And they would have given you a morning after pill to prevent preg.
Also to ans. Your question. I think it could be a couple of things yes preg. Could be one. Have you taken a preg. Test yet if not go ahead and take one since you are late. If it comes back neg. Get to a doc to make sure that it is nothing else ex. Std or anything else I dont want to scare you but anything is possible. Good luck hun.. And im here if you need to talk.
