I had that A LOT with my pregnancy with Olivia. My BH were pretty vigorous with her, and I am sure she was disco dancing on my bowel..........it just felt, from about 36 weeks (I went to over 41 weeks with her. A looooooong time........., LOL!) that between her, the BH activity, teh bowel movements, the bladder fullness, that there was just not enough room in my belly for it all!
