Seeing as I haven't started a thread for about 8 hours... 
Had anyone else had these? They totally don't hurt at all, just feel tense and tight, and contractions with DS were agonising. But they make me lose my breath a bit and go "oof!" and feel like a downwards pushing sensation right into my bottom.
I'm not sure if they are regular or not, as I've only just realised that they've been going on since about 9 or 10 this morning. I'm still not sure if they're the baby mucking about in there (it is right down in my pelvis anyway) or if it's me doing it, iyswim.
Anyone else?
