Yeah i also had a UTI at beginning of my 3rd trimester. I was put on antibio - maybe augmentin as well and it all cleared up. I was told it was safe to take during that stage of the preg, but because i get reoccuring UTI's - about 1-2 a yr i was put onto a kidney specialist and saw him a few times throughout the rest of the preg (still seeing him actually!) Hope it all clears up for u
