Hello everyone?

Hello everyone ?? I've been in the hospital for two days now with suspected pyelonephritis (the doctor will only be on Monday). I was admitted here with severe back pain in the right kidney area and a burning sensation during urination, like with cystitis. They're giving me amoxicillin, saline solution, and painkillers. I wanted to know if this would affect my baby somehow? I'm very worried about him ? I tried to refuse antibiotics but the nurses in the hospital are very principled.
