Random dull aches /cramp on one side

Emily

I know that i don’t have an ectopic . I’ve seen the baby. I am around 9.5 weeks .

I’m getting random dull aches on one side . Happens to be the side that the baby was on during the ultrasound . Is this round Ligament ? Can you feel it this early ? It started a couple of weeks ago. It’s really random .
