Lost...

Never went into labor naturally, I was induced with my first two so I really don’t know what to expect. I am currently 3cm or at least I was last week at my appointment and last night I lost some of my mucus plug and had contractions through the night. I am 39 weeks today and since yesterday I’ve been having contractions mixed with pain across my entire stomach. The pain feels similar to the cramps you get right before a period but I feel them everywhere not just in the pelvic area. I am set to get induced Thursday but this pain isn’t going away and I’m contemplating if I should go in now since I’ve been feeling this way since yesterday.. can anyone help, and tell me how they felt when they were in active labor at home... as far as I know my water is still intact.
