I thought I knew what Braxton HIcks felt like - I'm 38 weeks pgt and I've been having them since 20 weeks and this is my second pregnancy. But since last night I've been having Braxton hick-like tightenings across my bump that last for anything from 10 minutes up to 25 minutes (that is each 'hick' if that's the right word goes on for 25 minutes at a time!! ). I also had period pain type cramps in the night for a few hours - but these have gone away now it's morning and I'm back to the longer-than-usual painless tightenings.
Drinking a glass of water didn't make any difference.
Any ideas what this is?
