Hi, so I was recently told that my pee was very bad and I have a very bad UTI INFECTION. I'm scared because the pills and liquid form of medication are making me gag like crazy, and I throw up the liquid so I feel as if I'm not even taking it. This feeling isn't good for me at all. They told me if I don't take it, I will miscarry. I'm trying my hardest to digest the pills and liquid form of my medication but nothing is working. Can someone please help me.
