My baby has always sat low and ill be 24 weeks tomorrow
My baby chills at the bottom too lol. At 20 weeks the top of the uterus is level with the belly button but I felt it mostly at the very bottom, like in my bikini area lol. I'm 23 weeks almost 24 now and I'm just now starting to feel her in the middle. :)
My baby likes to hang out quite low too... I'm 23 and a half weeks and she is still pretty low but moves around a lot... My poor bladder hasn't been getting much of a break tho!
