Labor Or What. Please Answer Naman Po

Hi mommies. Ask ko lang po im in my 40 weeks and 3 days does labor means masakit yung pelvic mo? And bumabalik sya after 8 mins? Last check up ko. I have just plain blood in the morning and in the afternoon yellow greem na discharge. Dunno if manganganak na ako. Last june 3 kasi 1cm palang ako. Thank you
