I’ve had a very mild UTI. Lab test and swab done last week and they prescribed me antibiotics without the results. I had slight irritation when I was peeing that was it. I’ve nearly finished the antibiotics and woke up with low back pain. I don’t know if pregnancy related. I’m 23 weeks. If it’s a minor UTI would it have caused back pain. When I move it eases which is making me think it’s not to do with UTI. I took a home test to check if cleared and it’s showing as negative. Anyone had a UTI during pregnancy?
