Labor soon? FTM

36 weeks, being induced at 37.5. Was checked Tuesday and 2cm dilated and 50%thinned. I know it’s very possible to stay 2cm for awhile, but iv been having cramps for a few weeks now. They are slowly getting worse. Yesterday they were more intense than before, and this morning i was woken up by one that was even more intense with lots of discharge after it. So they are increasingly stronger. I had diarrhea Sunday all day, yesterday and today. Is this possibly labor coming soon or can this happen for weeks too?
