hi there. i have been having some current concerns, i switched my birth control to Loestrin, a low dose birth control pill, and since i have switched i noticed small white puss filled pimples in my bikini line and around my outter lips of my vagina. the pimples went away in one day, but now the inner lips are red, swollen, and itchy. i've had these symptoms before, after having sex. the day i switched my birth control, two days ago i had sex 5 times. so i have been guessing that the red, swollen, and itchy symptoms are from having sex too much, but i'd just like to be safe. i was just tested a few months ago for STD's and i was clean. but i'd just like to explore other opinions before contacting my doctor. i have done a lot of research on this the past couple days and have found i could possibly have a Yeast Infection though i dont have the discharge as one of my symptoms. I have looked at symptoms of Chlamydia as well but i dont have many of those symptoms either. what in the world is going on?
