I had strong Braxton Hicks with all three of my pregnancies starting around 5 months and getting uncomfortable around 8 months. At almost 35 weeks, I went to the hospital with my first thinking that it was labor, they sent me home and he ended up coming a week later. I had always heard that when you go into labor, you would know. Well, they induced with #2, so didn't have to worry about "knowing", and with #3, boy were they right!!! You will definitely "know" when it's time. When you get to the point that you can't sleep through them and can't walk through them, then you know it's really time. At least that was the case with me. And yes, I did unfortunately have contractions for weeks, and it brought much anxiety, especially with the first. Try, try, try to relax (I agree with Momof3girls, have a glass of wine and a nice warm bath), get as much rest and quiet time as you can. In a few days or weeks, all that stops abruptly!! And CONGRATULATIONS!!!!
