12 days overdue-2nd dose of cervadil

Anyone else experiencing this or have any advice? I'm 12 days overdue, started cervadil yesterday and didn't progress from 2cm when I went back in today. Got 2nd dose of cervadil and sent home.... again. Back tomorrow unless things start happening. I have been having contractions on and off today since about 9am. Manageable pain wise.... but oh so frustrated at this point. I really don't want a c section but I'm afraid I might be heading for one.
