Week 6-7 no cramping at all should I be concerned?

I had major cramping week 4-5 but since week 6 I’ve experienced no cramping in my uterus just on and off dull sensations/movements and prickly sensation in my right and left ovaries on and off.

After I have finished work I feel exhausted and have lower back pain im on progesterone 800mg per day due to past miscarriages. Is it concerning that my uterus isn’t cramping anymore.

I took a pink dye test and my test was lighter pink took clear blue digitally it says 3+ any one else experience this and have a healthy pregnancy/ baby?
