Low slow rising HCG and low progesterone

Did anyone here have very slow rising HCG levels? I'm high risk (3 losses, 2 live babies that were both born prematurely) I also have PCOS which causes my ovaries to be crap at producing progesterone (hormone needed to maintain pregnancy) I always test SUPER early due to the fact I need progesterone supplements and need my blood levels monitored. I got my first positive test October 27th (next period was due Nov 2nd) I had light spotting which turned to a light flow on the 29th and 30th so I called my OB and got in on the 31st. On the 31st my HCG was at 31 and my progesterone was only 2--which is bad in healthy pregnant women it should be over 10 in the first trimester) was started on supplements and went in monday for repeat labs. My progesterone is 3 now. Still super low but going up progesterone supplements were increased. But my HCG which is supposed to double every 48-72 hours was only at 36. Meaning in 96 hours it only went up by 5.... no other symptoms of loss (cramping fever chills bleeding etc.) Based on my LMP I am 5+1 today. However based off my tracking app (didnt use opks) I didnt ovulate until the 19th which would put me at 4+4 today. So super early still but with my OBs throwing out words like miscarriage, ectopic pregnancy and blighted ovum I cant help but be terrified. So has anyone here experienced anything similar?
