Pain in upper abdomen

I had my 30 week ultrasound and I asked the doctor about some pain I was feeling about 2/3inches above my belly button. It is localized to one spot.

It started in the past few days and of course googling it gives me all these terrible possibilities.

The doctor wasn't concerned at all which is a good thing but I'm still nervous about it. It gets worse over the day usually but this morning I already felt the tinge from it first thing.

Has anyone else experienced this? I'm going to call my OB in a few days if it persists but wanted to see if anyone else dealt with this type of issue.

Thanks!
