Membrane Sweep - major pressure/cramping

Hi,

39 weeks today. Had a membrane sweep yesterday at 5:00pm and today have had nothing but cramps and a lot of pressure. It feels like I need to go to the bathroom every 10-15 minutes because of the pressure and it almost hurts to pee because of it. Laying down doesn’t help. Anyone else have similar experience? I’m hoping it’s a good sign but also know lots of people who had nothing happen after the sweep. Thanks!
