Medicine question ladies!

Jordan
So I'm pretty sure I have a UTI. I'm leaking urine, uncomfortable feeling down there, can't quit peeing, constant urge to pee, all the basic symptoms. My doctor is a very busy office and I've had two other bacterial issues with my urine in this pregnancy. It's probably going to be about a week before she can even get me in. I was wondering if you ladies had left over amoxil from the other two infections and thought you had a UTI, would you take the medicine you found for it? If I go and I do have one, which I'm almost 100% sure I do, she's going to give me Amoxil 500 mg twice a day, and I already have a prescription here that I never took. I was just wondering if you'd break down and take the medicine for relief.
