Blood In Urine During Pregnancy

Hello
We went on a lot at my last prenatal appointment and my doctor said I had white blood in my urine. He said that this was not a big deal, but think of me wondering what this means? Why are they here?

Thank you in advance!

This means that you're immune system is working and you're body is working harder to fight against something off.

I was told that too ... Have you wondered what he did, etc.? xx
