Okay, 3 nights ago my boyfriend and I had unprotected sex. Ever since then I haven't felt like myself. My lower abdominal are has been hurting extremely bad, I constantly feel like I am going to throw up, I have to pee every 20-30 minutes, and I've been having lots of discharge and headaches. Could I be pregnant?
In only 3 nights you wouldn't be having any symptom of pregnancy at all only as the egg wouldn't long of been fertilized and at implantation stage the only thing you may have is a tiny bit of implantation bleeding. If you don't know how reproduction takes place and how long it takes to happen them you shouldn't be having intercourse until you also learn about contraception either.
