HELP ! Is this labor?!

Er

I have been cramping for almost two weeks now. Today i woke up and have been cramping even more than usual. The last 5ish hours i have had about 30-90 second long contractions every 10-15 minutes. They are uncomfortable and painful but nothing I can’t handle. Is this early labor? If it gets worse I will call my OB but I just wanted the thoughts of women who have experienced this before. Let me know what your guys think!
