You should definately keep hydrated but I wouldn't worry about it a lot. I have had BH since about 26 weeks, and 32 weeks is about the time they started to become pretty intense and sometimes constant, as you are describing, especially if I wasn't hydrated or was on my feet a lot. This is my third succesful pregnancy (I had two early miscarriages so it's my fifth technically). My sister n law is on her 3rd pregnancy and around 30 weeks and having the same stuff. You are supposed to be much more sensitive to BH with each pregnancy so that probably adds to it. I am 37weeks now and occasionally have a painful contraction but I have a ton of tig htening and BH, sometimes it's almost constant for days and then in subsides.
