40 weeks pregnant and labor?

So this is my second pregnancy, so I know what contractions feel like. I was definitely having them this morning for 2-3 hours, and they were regular too. I decided to snuggle with my 3 year old since they weren't intense. We fell asleep for about an hour and when I woke up, I wasn't having any contractions, just a little bit of cramping here and there. I've started bouncing on my yoga ball and the cramping has gotten stronger. Could this be early labor or false labor??

Update: started spotting
