Mild tightening + cramping the past 16 hours — BH or beginning of labor?

Allie

41+1 weeks and have had mild tightening with cramping since 4:30pm yesterday. Not very painful at all, and can only really tell by feeling my bump get hard. But have been pretty consistent every 10-15 minutes this entire time.

Really hoping this is the start of real labor, but getting frustrated it’s not progressing into anything more serious.

Anyone else experience anything similar? I haven’t had BH this entire pregnancy, so not sure if it could just be that. Someone tell me some good news!
