I’m taking metronidazole for trichomaniasis, I know that the kind of test they have taken is 40% chance of being wrong as both me and my boyfriend have been 100% faithful in our relation, and if I had trich for more than two months it would have shown up in my three urine samples the month before the swab as we didn’t have any sexual relations for two months before the swab was taking, I am 35 weeks pregnant and would like to know the side effect or risk of taking metronidazole if I don’t actually have an infection, could it harm me or my baby? Should I keep taking it until my boyfriend gets tested, if he doesn’t have it I know that I never did, as we had sexual relation a week after the swab was taken.
