Hcg doubling

kay

2/8 hcg 169 progesterone 4.69

2/10 hcg 182 progesterone 6.90

No cramping, slight spotting 1 time.

I have had a miscarriage in the past because of low progesterone and needed to supplement the next pregnancy so I didn't miscarry. I have read that it is possible for hcg not to double properly because of low progesterone and wonder if it has turned around for anyone?
