Not too painful contractions… labor?

Sa

I’ve been having fairly consistent contractions, strong, but I can definitely talk through them. I haven’t been able to tame them very well because I’ve been chasing my other three little guys around, but they seem to be happening pretty consistently. Yesterday I was 80% effaced and 2 cm. Wondering if this could be the start of labor. 

With my first, he was sunny side up, so I had terrible back labor. My second was induced and my third I had other complications and didn’t know how far along I was. This has been a super easy pregnancy, so I’m wondering if the labor is just starting off mild!
