First ultrasound went great

Saw my little peanut and his (or her) heart was beating perfectly so in love ! Suppose to be 8 weeks 6 days according to my last period baby measuring 8 weeks 4 days so right on track... Due date still set at sept 14th 🙂
Also found a huge cyst ! But he said this is normal so we will just leave it there haha 
After he did my pap and ultrasound though I did get awful crampy anybody else experience this ? I don't think I ever did with my last pregancy
