CLOSE CERVIX AT 39.3 weeks

Hi Mommies! Ask ko lang, April 4 (this Sat) na ang EDD ko but as of Mar 30, close cervix pa din ako. Next visit ko kay OB would be April 6, ang sabi niya, if normal pa ang level ng amniotic fluid ko, hintay pa for another week. Pero kapag mababa na level, i-CS na niya ako. Ganoon ba kabilis mag decide for CS? Is there any recommendations para mag bukas ang cervix for my normal delivery? Nag ta-take pala ako evening rose oil for 3 weeks na. Walking and squatting are part of my routine na din.
