Waiting For The Best Day ?

Hi mommies, please enlighten me. I'm at 37 weeks & 4 days na po but still no signs of labor yet. Nagpa BPS po ako nung March 20 and Cephalic na position ni baby, since walang pre-natal check up may mga chances po ba na magbabago pa ng position si baby like maging breech? Worried lang po and paranoid though this is my 2nd baby na. Sana po may sumagot. TIA momshies & Godbless ?
