40 weeks today now! Due date!!

For the first time in my pregnancies I had made it up to my due date. My last two pregnancies I had both my kids at 39ish weeks but not this time! I had a doc appointment on Friday and was told to be 2 cm ... lately been losing my plug. Before 12 am today I finally had pains which to me feels like I have a really bad stomach ache. I’m having the usual stomach cramps along with the runs so .. I had nothing but candy and jalapeño peppers and then leading to pain which lead me to believe I messed my stomach up. Now I feel like it turned from stomach ache to contractions... so idk what is what but it sure hurts and my stomach is tightening during each “stomach ache pain” and its happening frequently! I want to believe it’s time! Is it time? What do you think at least??
