Okay, so I went to my OB/GYN on Monday because I was having some yellowish-gray discharge, and it's been going on for about a month. Originally I thought it was a yeast infection because my discharge started out white and clumpy and I was having some itching (sorry for tmi), then the discharge turned to yellow about a week or so later. My primary care doctor didn't do any cultures, but he treated me with Diflucan (2 pills) based on my symptoms because I've had one yeast infection before. That didn't work, so he suggested cultures through my OB/GYN. She said that I had a bacterial infection and she put me on Flagyl. Well, her office just called today and said that I have Trichomoniasis, which I don't understand how that's possible if I haven't had sex in over 2 years. My partner at the time wore a condom and everything, and I honestly wouldn't even call what we did real sex because I told him to stop not even a minute into it because I was in pain (it was my first time). I've had guys finger me and stuff like that, but I haven't been sexually active in the literal sense since then. I did give my boyfriend oral one time without a condom, but he's never been with anyone else before, so how could I get it from him?
I'm still on the Flagyl and I will be re-tested on March 28th. The nurse that called me back today said that this isn't something I should worry about and that I'll be fine. Is this true? I just don't see how this could happen, and now I'm scared. Has anyone had this?
Also, the pelvic exam yesterday was very uncomfortable -- I was in a little bit of pain while my doctor was taking the cultures. Is this normal, especially now that I know I have an infection? I just had a pap smear in August and that came back normal, by the way.
As a side note, my periods have been a little "off" for the past two months -- In January, my period was one day late and the bleeding was slightly lighter than usual, and the last two days were basically spotting. My period for February started 2 days early and full on bleeding only lasted for 3 days, and then I had spotting again for probably about 2 days. My periods usually last 5 days. The last time I had any kind of sexual contact was in December, and even then my boyfriend only fingered me. I was naked but he had his boxers and jeans on, so I know it's impossible for sperm to travel through clothing and result in pregnancy or any kind of STD transmission, so I don't understand what's going on.
