Abdomen pain at 10 weeks ?

I have had sharp pains on and off from 4 weeks and on and off period like pain but i have found them worse this week. I'm also getting a pain in my groin down my right leg I had this once for like 5 min in my 5th week now I've had it 2 days. I'm not bleeding or anything. Anyone have this? I'm not ectopic I had an ultra sound at 7w5d and saw the babies heart beat and everything fine.
