Progesterone and hCG

So I went for blood work Monday and got my results back today. My hCG was 215 and progesterone 14.23. I go back tomorrow to make sure my hCG doubles but so far seems right on track. Got my first positive last Tuesday on a test that has a threshold of 25. So Thursday would have been around 50, Saturday around 100 and Monday around 200 and it was 215 so that seems to be on track. She also said my progesterone was looking good but now I am paranoid because people on here are saying if it’s less than 20 then they needed a supplement. Just wondering why my doctor would have said my levels looked good. I’m a little over 4 weeks I think but not sure since my cycles vary. Anyone know?
