Minor cramping?

Kristina • Married to the love of my life with two beautiful sons!
So I lightly poked around my stomach 2 nights ago with my doppler like the doctor does,minor  pressure but nothing super hard and now today I have minor on and off again cramps. I am assuming it is just a coincidence and my uterus is just stretching rapidly as I am about to hit 12wks but just thought I would check with you lovely ladies!
