Prodromal Labor?

Ma

The past two nights I’ve had somewhat strong contractions that last about 40secs-1min, they are 15-20mins apart and go on for about 1.5-2hrs. I’m thinking it’s definitely prodromal labor cause I’m still a little early at 36w5d and nothing has progressed yet.

Anybody have experience with this or advice? Did it start weeks before active for you or only days? This is my third pregnancy and my youngest is only 18mo.
