I am currently 26 weeks into my second pregnancy (last one was 4+ years ago so memory might not be as great for that period as it cold be). For the last month I have been having what I assumed are braxton hicks (I feel my abdomen tense up for up to a minute. It isn't really painful I am just away of it).
I don't recall ever really having them when I was pregnant with my son and definitely not this regularly (maybe one a day). So do you get them more in second/third etc pregnancies?
