Not sure...was there any pain involved? Could it have been a hiccup or just a result of baby moving into a different position? They don't have quite as much room at this point, and I can remember hearing all sorts of strange noises, and feeling odd movements at this stage. If it's painful or concerning, give your Dr. a call. Congrats on your babies soon to be appearance! So exciting!!
He was moving n it was just like a pop I guess felt like a water balloon kinda I never felt it before n it didnt hurt I thought maybe it could have been my mucus plug came out or popped a little bit but no sign of anything thank you for responding!
