Opp. I feel stupid. I thought that was a joke question.. i didnt even think of answering it like that. Lol.
It really depends on the person, but your uterus expands past your belly button now! I'm 22+3 weeks and I'll feel some movements above it, but mostly she likes to stay low. Hope that kinda anwsers your question
..... 21 centimeters from the top of your pelvis is where the top of your uterus should be, he's in between the top of your uterus and the top of your pelvis. But yes, the smarty pants in me was thinking "in the uterus"
In your uterus.. they stay there the whole time..
