FTM - Contractions or something else?

First, let me preface this with that I have a doc appointment today at 4 and I’m scheduled to be induced tomorrow at 9 am, on my 38th week. Diagnosed GD.

So last weekend, I started feeling intermittent cramps paired with backaches. Not painful enough that I couldn’t talk or function through it, but noticeable enough that I went to Triage JUST in case. Baby’s good, I’m good, sugar level is perfect, cervix closed tightly but nurse/doc attending both said it could be the start of something or just need to drink more water (guilty, was not monitoring that intake as I usually do).

Come Monday, started losing my mucus plug in like long stringy pieces. Happened a few times I went to the bathroom, then stopped. Had an NST appt, baby still looking good and my vitals are good. Same thing Tuesday, minus the NST. Wednesday, I’m perfectly fine, no mucus plug loss and very minor cramping.

Today, I have started to feel more cramping, definitely a bit more intense than before as I can’t get comfortable or find relief, and I’ve had 3 in a span of 2 hours. Each lasted over 2 min. All accompanied with back pain. Now I’m wondering if I should call my OB and see if I should go to triage, or wait it out until my appointment with her and go from there?
