HCG blood test at 7dpo

Cait

Has anyone had blood work done on Day 21 of your cycle (7dpo)? When did you get it done? Was it accurate/inaccurate?

My doctor ordered an HCG (along with other panels I couldn’t get done due to a lag in insurance) and it came back <3. I just thought that was super early to do a blood test, but I could be wrong since I know they’re sensitive.
