My boyfriend and I have been together for 2 years. We've had unprotected sex only two times and I have been tested for everything in the past and all tests have come back negative. The last time we got together, which was between July 12-18, we didn't exactly have sex. We only made sexual contact twice during this time. The first time we just rubbed our genitals together, but he did not penetrate me. The second time we rubbed our genitals together, he penetrated me, but pulled out right away.
A couple weeks later...probably the first week in August, I get my period. After my period, I notice that my discharge was yellow, smelled different and I seemed to be a bit irritated down there. Normally, my discharge smells sort of like Apple Cider Vinegar before and after my period. This time it smelled a little fishy but only after mixing with my sweat. The initial smell wasn't the worst thing I've ever smelled, but it was just odd. Sometimes it would just stink, and then other times it smelled specifically like sour milk or a bit fishy. Besides the discharge, color and slight irritation, I don't have any other new symptoms.
I've dealt with chronic BV for a while, but I was able to get rid of it for a few months ago after taking probiotics. I admit I kind of started slacking on taking my probiotics toward the end of July and then I started using a feminine wash that I normally don't use.
Does this sound like it could just be my BV that's coming back or could it be an actual STD like Chlamydia or Gonnorreah or something?
