I only just noticed that I've been having BHs the other day at 37 weeks when I was lying on my side and I said "oh THAT'S what they feel like." I guess I had noticed my belly tightening before, but I thought it was the baby having a big stretch. It's really just an overall hardening of my entire uterus that is very easy to deal with.

Around 31 weeks I had one experience one night when I woke up with strong period-like cramps that made me go and I thought that was a BH, but it happened only once.

Then lately I've had some cramps across my lower abdomen when I'm lying on my side in bed at night before I go to sleep, so I wondered about them, too, but now I'm getting close and baby's full term I'm just thinking "general pre-labour".

I don't know why, but I seem to only notice it when I'm lying on my side. Weird.
