From about 18 weeks to 27 weeks I had a lot of braxton hicks contractions. Pretty regular. In other words if I stand, walk, bend,.....move. The problem has been that when I get them I also have pressure on my chest and lungs and it makes it hard to take a real breath for a moment. My midwife said not a problem. Well last week it stopped. Now when I get braxton hicks I instantly get a ton of low pressure and have to pee immediately, even if I just went. A real pain when I get to the grocery store. Is this normal? I had a ton of BH contractions with my first pregnancy and it never bothered me in either of these ways. I did get checked for a UTI last week and it was negative.
