2 weeks ago i had my period i had gotten very drunk and a friend took advantage. Having sex with a tampon in, he wore a condom and didnt finish i know he doesnt have any sti's. But the next morning the tampon was still in i had gotten it out. i still had my period for a couple more days but i had to use a different brand that was to big and the absorbency was very high while my  period is pretty light. Ive noticed a couple little painless bumps in the opening of my vagina they arent growing in size or changing. please help
