This afternoon after a long time standing washing dishes, I suddenly realized I havent used the bathroom in a long time. After going I had this super strong pressure in my low abdomen, near my bladder but kind of across the whole bottom of my stomach. My friend told me its uterus stretching pain. Anyone have similar? Its not really cramping, but pressure. No spotting, no other signs. I wondered if it was dehydration. Im only 8 weeks and it hasnt let up all evening.
