Am I in labor

Labor with my first started with my water breaking. Last night I was woken up by two very obvious contractions about 10 minutes apart. It was wasn’t just tightening, it was painful like a wave of period cramp pain. I had a few more somewhat painful ones following but nothing super consistent. I fell back asleep and just woke up really sweaty and crampy. Baby is moving more than usual, and I have pressure on my vagina. Also just this constant tight feeling in my uterus. Is this labor starting. Very different from my first time around where it was obvious.
