Where to get hcg tested?

B✨

Hey y'all! I just found out a couple days ago that I'm expecting! According to my LMP, my due date would be September 30th so I'm at 4 weeks right now. My OB scheduled me to be seen at 7 weeks but I'm such a nervous wreck! I want to make sure baby is doing well and my levels are rising, waiting three weeks is like an eternity! Should I just contact my PCP and ask if she can test my levels?
