I don't know that sounds weird. Never felt that before!!
I know when shes hiccuping and it doesn't feel like that, it literally feels like if ur phone was setting there and vibrated lol
I can feel my baby's hiccups in mine. Her head is on top of my cervix lol I feel violated!
Omg I felt that twice I thought I was trippin so I ignored it
Maybe your vagina fell asleep ( like it feels when your hand or arm falls asleep?) Because I honestly have no clue maybe it was baby hicupping(:
