Uti at 32 weeks

Went into the ER today due to a small amount of bleeding. They noticed my urine was a bit cloudy and decided to test for a UTI. They also looked at my cervix and it was closed and the babies heartbeat was normal. They said the test was suspicious of a UTI but they sent it to the lab for further testing and will get back to me tomorrow about getting medication to treat it. But I have to say it's still so alarming to wipe and see blood. I also didn't even know that I had a UTI as O had no symptoms at all. Did any of you ladies go through this? If so how long did the bleeding last?
