Early pregnancy cramps ....

Hi all....

Just want some insight on what others felt.

I’m at 4weeks 2 days, having cramping /pulling on off. Freaking out slightly (maybe paranoid) that I feel it more on right side. My worry is an ectopic pregnancy. 1st scan is 12 weeks and you don’t know until it’s too late. 😬 anyone pay for ultrasound to confirm?
