Yeah was probably a punch or a roll of your baby is head down. My son has been head down since 29 weeks and you can see him roll and it feels really weird I even feel his hiccups below my hips
Im 29 weeks also and i feel the same im also thinking its breech. But i am still not sure my ultrasound on 10 so i wll find out soon.
It's probably a punch rather than a kick. If she's head first, her arms are in that area!
