Should I call doctor?

Tesha • BFP on 9/22
I'm 36 weeks 1 day today and my last appointment was Monday. My baby girl is very large, 7lbs 7 ounces and measuring 39 weeks. They were planning on inducing me at 38 weeks due to her size. Last night I had contractions every 3-6 minutes off and on until 3:00am. I've only had slight cramping today and one contraction so far. Should I call my doctor just to let her know or not?
