I tripped over my husband's tool box while i was carrying a basket full of laundry and the sofa shoved the basket into my stomach hard i was fine and baby
I have only fallen when doing laundry! It hasn't ever been bad enough to worry me. I'll usually even have the clothes in the basket. Pregnant women just shouldn't do laundry :)
You should go to er to get checked. Any trauma can be potentially dangerous. i dont want to scare you, it is probably nothing to worry about, but you should go get checked just in case, you will feel better once you know everything is ok.
