Ever since I had sex this past Saturday, I've been having an excessive amount of liquid discharge. At first it was clear and then I was spotting as if I ripped or cut something inside my vagina and now the discharge is yellowish. I just had a pap done on the 17th and the doctor told me that it was normal. I also feel a little pain as if there is a cut down there. Thinking that the discharge may be coming from a bacterial infection or something, I refilled my prescription for Metronidazole. I used it last night but I'm worried that it may be something else and that I need to see a doctor. Should I be seen about this or is this normal?
