Membrane Sweep today at 39w

A • expecting baby #1 March 2015!
Headed for my routine OB appt today and she will be doing a membrane sweep. Last week at 38w i wasn't dilated at all, been walking a lot and trying all the old wives tales for self induction ;) bouncing on an exercise ball, squats, eating pineapple, Evening primrose oil pills, red raspberry leaf tea, etc. Anxious to see if its helped but sooo nervous for the sweep and hope its not too uncomfortable or painful!! (This is my first baby)
