Rhiparry1 mine feel like slow running up tightenings, that get stronger and stronger and stronger, stick around for a bit then start to ease.... they do take your breath away! I was feeling my belly laying down as they happened and it was like i had a small boulder inside my tummy, everytime they eased off baby went mental kicking me and then went quiet as another one happend... Then i got tons of kicks in the cervix and was crapping myself that my waters would break as baby was really bouncing off the walls!
It just creeped me out cause i honestly didnt notice them when i was pregnant with my son til i was much further on and only after sex.
