please, i really need help. i have been tested for STDs and they came back negative. i just got off doxycline (idk how to spell it correctly) but i used it for a stubborn and painful kidney infection. i havent had sex recently enough to have it be friction irritation. i did use a super plus tampon when i didnt have that much flow and irritation started after i pulled it out. the redness calmed down for a bit but this morning i felt the burning sensation. no other symptoms such as discharge. i am on my period currently though. i have taken the yeast infection pill though at 3 pm and it is currently 10 pm. i really need help and am very confused.
