Yeah... When you are laying down, the top of your uterus kind of feels like a cliff. It will be a hump that falls off obviously. Usually it has that sloping feeling because that is where a baby will tuck a butt or leg or other part. Another way to know you've found the top is that if you push on surrounding organs, it feels squishy or sometimes a little sharp pain. Gosh I hope that made some type of sense!
Namaste, Tara
