I decided to walk to work today

Decided to walk to work today. I'm 37 + 1 and about 2/3 through the walk started getting bad pressure. Having menstrual cramps. Belly cramps and back pain and major booty pressure. Today is a 12 hour shift so I still have about 10 hours left. I'm hoping that this means I will go into labor soon. I'm wanting to do the natural thing instead of being induced this time and going to be induced in 1-2 weeks
