Of taken my last pill. I had sex with my boyfriend. He then tells me that ever since we had sex when he urinates it burns. I then thought it could have been trichmonias since drs can easily get mistaken for bv or trichmonias. The nurse tells me i was tested for both nd i was negative for the trichmonias just postive for bv. Im negative stds. Could it be that my medication triggered my boyfriend burning sensation while he urinates? Please help im worried
