My lil one was still moving around a it until the night before she was born, they can move a bit and sometimes like to punch or kick down low, sometimes even headbutt.
With breach i am fairly sure they let you go full term and then do a c/s, my lil one was breach but we didn't know it and i had her at home on the bathroom floor, i was told she was engaged from 2 weeks before i had her... little turd turned... lol
Her birth story is on here if you would like to read it, Ava's unexpected breach homebirth.. lol

I hope all is well and bubs is just throwing in a few punches.
