You GO girl, I'm having some today too, and I jsut started with BH last week and these are definately different.
What I was told by my Bradley instructor is this: any contraction is a real contraction hypothetically, they are all working at the same goal. However, if they are coming on, and feel regular etc, and you change position (like you are sitting and start walking) or eat and drink something, or go for a walk, and they are still coming, then it may be pre-labor/labor vs. BH. Does that make sense ? The other day in the car I was having BH every 5 mintues but they were quick, essentially painless, and just hardening. I knew they were nothing. Today and yesterday I have been having very irregular, hard to describe, cross between period and diarrhea cramp feeling things, the pain comes, it IS noticeable, sometimes mildly breathtaking, the pain subsides, and THEN my belly gets hard. So I have no clue what they are. My back is involved sometimes, and last night I was awakened by 2 or 3. But they are not increasing in intensity, and they are not getting longer (and they feel pretty long) so I am trying to ignore them and hope for the best, if that makes sense.
I am sure the other ladies can give more info since I NEVER had a real contraction last time, Pit or not.
I hope this is it for both of us, you first tho LOL
