38 weeks & stuck

Florence
At my last appt my doctor told me do whatever I can to kickstart labor since the baby is 8+lbs by now. I'm normally very active but within the past few days whenever I walk the baby rests on some type of nerve that sends a shooting cramp from my butt muscle all the way down my leg...it literally causes me to stop and grab onto the nearest stable object otherwise I'd totally crumble. I would love to walk more but lately all that I've been doing is resting because it's too painful to walk. I'm so frustrated! I know just laying down for most of the day isn't beneficial to me or the baby and probably isn't moving anything along. Anyone else feel like they're stuck as well?
