Apparently, a gallbladder attack can start up contractions. The reverse is not true though. Thank goodness or I'd be considering dates for a c-section. Good times, talk about a confusing rush of sensations! Attack number five came the other night along with some lovely tightening. This was my first time to feel contractions of any sort, so I wasn't sure if the event called for gallbladder pain meds or not. It did. Pain was gone after the meds wore off, so I'm good now. No more pork loin for me.
