Not sure Beema, dd1 was breech bum first and mine were only in the back I only felt them in my tummy for the last few ctx before the cs, but maybe it's because we were both early?

I felt the ctx in my belly with dd2 at 35 weeks, she was engaged though.
quite possible, I wish this sort of thing was consistent so we knew either way

quick call to the OB might be in order too.....
her office opens at 9:30am so will give them a call and see
