ttc- period like cramps.... looking for experience

Kylie
Is anyone in their tww experiencing or has ever experienced period like cramping?... I am 7dpo and have had dull period like cramping since 1dpo .... this is so out of the ordinary, I'm not sure if I need to be concerned or not.... also no clue what is going on. 
I am 17 months post emergency c-section and we are actively ttc!
