Multiple UTI's help :-(

Kyla
I have never had a UTI before. Not with my first pregnancy either. Now with twins, I've already had one and I think I have it again! I drink so so so much water. (Always have). I use the restroom at the first instant I have to pee and try to make sure I've emptied tithe best of my ability. Any suggestions? Anything safe to take? Cranberry pills? Do I have to get another antibiotic or are there any safe home remedies? I will be asking my doctor Monday. Just need relief til then
