Advice about Primrose Oil

Kirsten

My OB said I cannot go past 39 weeks - I have to schedule a C-Section. She did say tho if I am laboring or starting to dilate before I can continue and possibly skip the c - section. Also I'm measuring 3 weeks ahead. Currently, I'm 31 weeks when would you start ORALLY taking primrose ? My first baby I didn't dilate nor efface AT ALL on my own.
