Urine smells bad? TMI

I’m almost 38 weeks pregnant and JUST got off antibiotics and noticed my pee smells like sulfur? Rotten egg smell? It’s not my vagina because I wiped 10 times and kept smelling the paper to make sure so all I can think of is the smell is coming from my pee? Obviously not a UTI or a Infection. I’m thinking maybe a imbalance of bacteria in my pee? I’m going to try to drink more water and drink some more probiotic yogurts and see if that helps! Has anyone else experienced this before?
