Kittycat, I do think your concern has some ground, prog peaks at Day21 and 23 is not high at all. I remember when I first start seeing Acupuncturist and she asked me to test D21 prog, mine was 30 and she said its on the lower side. Also early AF is a sign of lack of prog support for luteral phase. Definitely check with your FS and don't give up. Best of luck!
