Is this progesterone number low?

I am 6 wks pregnant and went in for bloodwork yesterday. My hcg is 1423 and my progesterone is 11. When the dr called, she told me my numbers looked good (she didnt tell me the actual numbers, I looked them up through the patient portal later)

I'm wondering if my progesterone is too low though....especially bc I'm spotting (this is around the time I would have had my 2nd period after conception, and I spotted quite heavily around when I would have had my first period.)

I go back in tomorrow to test my hcg again, but not my progesterone, and then I have an apt with my dr on Thursday.
