Someone is stabbing my belly button

At least that's what it feels like. Every 5-10 seconds it's a super sharp pain. I went to get my ultrasound this morning and everything is fine. Is there anything I can do to make this stop??? The lady didn't say much about it. I'm only 18 weeks so I can't deal with this for the next few months.
