The past week I had unprotected sex with my boyfriend. We did it about 3 times around the 2nd time it started to hurt it was my first time having that muvh sex in a day. Well the next day my vagania was hurting and itching it felt sore like underneath my vagania I had little goosebumps I thought it was a rash kaused by the roughness and 3 times. The next day I got yellow stains on my underwear like yellow bright. And the follwing day I got yellowish greenish discharged on my underwear it smelled like cum so yea. By that time the itching and burning wasn't hurting as bad. Around friday the discharged went away I started changing my underwear and wearing sweat pants the pain had went away saturday so did the itching and burning. And by today its gone. Can this be some type of STD early symptom? A yeast infection? Rash or what? I'm really worried and would liketo find out as soon as possible
