i recently started birth control and about a week later developed a rash. i assumed it was the liner i was using for the break through bleeding. i visited the OB and was prescribed diflucan for a yeast infection and an ointment for the rash. i used the oinment but not the pill as it went away. a month later (now 2 days ago) I had sex which caused discomfort and burning. I woke up to internal vagina pain and a small rash so i decided to take the pill for the yeast infection. Today i discovered the pain is coming from a small bump at the end of the vaginal opening. It looks like an open sore and discovered another one at the top that looks crusted. I have watery discharge and discomfort when sitting. Could this be an STD or bad infection?
looks like thrush
thank you! i went to the doctor yesterday to get tested and hes thinking its herpes 
this is an update! im getting worried it may be herpes. its painful and more blisters are appearing every morning
Definitely keep the area dry. Herpes is very common and you can take medication that will allow you to not transfer it, and have little to no outbreaks!
could you let us know the results i’m having a similar issue that is identical in appearance and like you hoping my results come back as literally anything else but i cant get in to get swabbed for another two days.
my blood work came back negative but the sores tested positive for herpes : /
