Blood in urine?

[bluedaisy]

My midwife has my pee in a cup each time and has a stick that tests for various things - for the past two months, it has showed that there is blood in my urine but nothing else.  The first time DH and I had had  sex that morning so she thought it might be a little bleeding from the sex.  Since there were no leukocytes present and I had no signs of a UTI she didn't think it was that.

But every visit since then there has been blood (about 5 times) and a few of those times we hadn't had sex in at least 24 hours.  She sent my urine to be tested over a month ago and it came back as inconclusive - i think the numbers were borderline or something.

So for the last two weeks I've been taking tons of cranberry but today there was still blood.  She sent another sample off today but she's not sure what is going on.

Any ideas what this could be?  I've had UTIs before and even though I pee all the time it's different than UTI - most of the time it's a significant amount and there is no burning or blood that I can see.

I'm 32 weeks and a little nervous since I've read that untreated UTIs can cause premature labor.

Bluedaisy, I've been having recurrent UTI problems this pregnancy and I haven't noticed ANY symptoms.  I'm having a consult with a urologist this afternoon-- I'll pass along any general info I get.  Otherwise, I'd love to hear other peoples experiences with this as well.
