This happened to me but I had a little more blood, I went to the hospital and they said I was having contractions. They stopped them thank goodness. I was 34 weeks at the the time. It was probably just him messing with your cervix but, I agree with her ^^ I would definitely mention it to your doctor just in case.:)
I'd mention it to your doc.. your 35w so chances are you just irritated your cervix! But it doesn't hurt to mention it to your doc!
