How to Get a Beta Test

Hi all

Just got a positive pregnancy test(yay). I’ve been tracking the line but wanted to go in and do the beta test. It’s currently Saturday so only urgent care is open. I called around and got conflicting results. They said I need a primary care physician to order the test for me and I currently do not have one. I thought it was a test I could just request but apparently not. Any tips or places you know on how to get it done. I want to make sure my hcg is increasing. The test I’ve taken stat about the same but I started testing before my missed period.

Thank you in advance
