I know they are normal throughout pregnancy and I started feeling hem early with my last pregnancy but today I was woken up by one in the middle of the night and I have had quite a few since. They aren't painful but they are make a  noticeable difference for me when I'm trying to breath, like I get short of breath... I called the OB but they are out of office till 1:30. Just wondering if Braxton hicks have felt like this to anyone else??
