Hey Doc, ok recently i lost my virginity and i am a 17 yr old female. we didn't use protection and there was oral sex involved. I'm a paranoid person and the guy has told me repeatedly that he was tested a month before and he had no problems. But not my vagina is irritated and itching and i have a sore throat only on my left side. Here's the thing though, I took Plan B, so could my irittation and what not be a result of that? or is it a result of me stressing cause i read on the internet that stressing can cause itching? or do you think it is just a simple yeast infection? oh and the sore throat thingy could be because for the past wk ive been falling asleep with my mouth open in cold rooms. That has happened to me before. I'm getting tested hopefully tuesday with friends. I just hope everything is fine so that I don't have to tell my mom about the stupid mistake i made when i wasn't thinking. i've learned my lesson. i just need awnsers. so can you help. oh and one point i had a bump (painless) in the upper corner of my left lip. Although that could be due to recent changes in weather (has happened to me before). SO let me know doc, are all these just ironic scenarios to be in, or do i seriously have something to worry about?
