trichomoniasis
"I didn't even know I had trich, I went to a birth control dr. Appointment and they asked if I wanted to do an std test and I said sure, they came back and said there was a very faint line but they wanna be sure so they considered it positive, they told me I was gonna take 4 500mg pills and I immediately thought my boyfriend had cheated but they said it lingers for a long time, after I took the pill I got a headache and then later that day I started getting sick, and then the next day I've been feeling nauseous all day, I had no symptoms of trich or anything so I can't say if it works or not, all I can say is it tastes nasty"
