I had sex with someone unprotected a few days ago.. could you have symptoms that quickly if he had something?
I'm pretty sure you can..it depends on the STD, some take years to be noticed, some just a few days.
Go get checked out by your doctor.
Always use a Condom so you wont worry about those things unless it breaks perhaps
unfortunately yes u could easily have a std if the person u slept with had 1.
u should always use protection to be on the safe side.
go to ure Dr or family planning and ask for a swab asap, the sooner u treat an std the better.
Good luck.
