Anyone else

37 And 3 and i swear im looking for any sign of labor. Im 2cm and 80% effaced. This is my 3rd baby and it been absolutely different from my other too. Last night i had contractions 20minutes apart for 6 hours with hot flashes. Then this morning getting up im feeling these cramps that feel like a menstrual period. Never experienced this before. Im super gassy and feel like my stomach is hurting. I don't want to cry "Labor" and be sent home. I drink two - two liters of water everyday. So i know its not from dehydration.
