I think I felt him drop, one night I was just laying there and then all of the sudden my stomach felt really light and weightless for a moment and then my lower stomach got really hard. it was on Sunday, I can breath better now lol, my ribs hurt less, and my boyfriend noticed my stomach was really low. I'll do some before and after pics soon. but does it sound like that'd an accurate assumption?
