Cramping at 10 weeks!

Paige • Mum of 2 beautiful babies 👶
Please don't just read and run I could really do with some reassurance 
I am currently 10+1 weeks pregnant with my first , following an ectopic pregnancy last year. Ectopic has been ruled out as saw and heard my baby's hb at 7 weeks.
I have been cramping since before I even found out.
These are period type cramps that range from barely noticeable to severe and stop me from doing certain things. And last from 1 minute - 30 minutes at a time. They are not constant but occasionally can be. 
Don't have my dating scan and booking app till next week and the cramps seem to be getting better then come back worse.
I'm really worried as thought they would be wearing off by now :(  
Any reassurance ladies?
