When I went into labor, I didn’t realize it because it was back labor. I had intense backache every 10/15min or so. I didn’t know back labor was a thing. I recommend calling your maternity office, they should have a 24/7 nurse available for triage and they will be able to guide you properly
I should add they aren’t painful just uncomfortable. I’ve also tried changing positions, drinking water and emptying my bladder but they keep coming
