I had loads from 30 weeks onwards with DC1 and DC2 - indeed, mine were so painful (period pain cramps to the extreme) that every single time I thought it was labour. The key is that they should be absolutely regular (not even a minute out), and intensify and get closer together over time. IF they don't do that, you're unlucky, like me, to have painful BH!!
They feel like someone is squeezing you really really tightly but you are being blown up like a balloon at the same time. They can take your breath away at times.
I don't remember them feeling particularly crampy though.
yes it's a 'tightening' like a taut balloon under the skin. Now that I am 31 weeks I can see the womb rising up and outwards with a BH.
TMI alert - after an orgasm your womb does the same thing, so next time you have one, see how the surface of your belly feels afterwards. Should be quite firm to the touch.
But they don't particularly feel like period cramps to me. They are totally painless IME and only last a few seconds, although I could easily have two or three in an hour.
If in doubt, give the MW a quick ring to check

. Have they stopped now?
ah so THAT's what I'm having! I thought it was the baby moving into a tight space

mine feel like a tightening - my belly goes rock hard and it is uncomfortable but not painful
if you are worried, or they increase in intensity you should of course ring the midwife
It's kind of like a tight feeling across your tummy, although my friend said hers went across her back...
Hi all feel a bit stupid asking this as its my 2nd pregnancy

I never got BH with ds so not sure what they feel like, I am 32 weeks with twins and for the last half hour have been having period like cramps and the odd twinge. Its not painful just annoying and I was wondering if its BH or if I should think about ringing the mw?
TIA
