i have had "loose bowels" most of this pregnancy (apart from when i was constipated for a few weeks) i am pretty sure i was the same with T the midwives i have seen at the hospital said it was most likely hormones and not to worry too much ....
that is great when i have the worst pelvic pain i can hardly stand up and everytime i sit down i need to get up and use the toilet
i hope you are ok
