I'm 15w 6d & i was doing some cleaning around and i literally picked a super heavy bag from the floor to my bed which I'd say was a few seconds, I did feel a little weird in my uterus and that freaked me out but that weird feeling didn't last long I felt normal after a couple of minutes. I read online that during pregnancy you shouldn't be doing any kind of lifting, could those few seconds of heavy lifting have harmed my baby?
