Having a vaginal exam is like looking into a crystal ball... it really doesn't tell you anything at all about when labor might begin, or how "easy" or fast it might go.
I declined any internal exams at all with my last pg.
I have *never shown any signs of impending labor cervically (is that a word? lol.) My first two births ended up on the OR unnecessarily. With my third, no cervical changes even in early labor. He was OP, and took three days of active labor to make his appearance (vbac.) My fourth, no signs at all at an exam at 42.5 weeks, I went into labor a few hours later, and she was born *easily a mere 8 hours later!
This last time, as I said, I just declined altogether.
I've actually heard of cesareans being scheduled after mothers have been told by doctors that the baby wasn't engaged, long, thick, hard cervix, and that baby was obviously not going to ever come out the vagina. Poppycosh! Again, an internal exam has NO bearing on how soon or easily your baby will come.
Try not to stress, your baby will come will he/she is ready, whether or not a doctor says so.
