Didn't want this to get lost. I just saw the article you posted. Thanks for sharing. Although there is a part in the article that says approximately 80% of pregnancy where P4 < 10 abort and virtually no pregnancies with <5 are viable.
I'm still keeping my fingers crossed for a miracle. I go back next week for u/s so we'll see if it's still growing in there.
I saw that part of the article too, but I am absolutely CERTAIN it is referring to the P4 level taken at the first beta (usually at 4 to 4.5 weeks). Your pg is at that transition stage where the placenta is taking over, and I see from the graph that it can drop lower then. But you know, most people stress about betas and P4 as predictors of whether they will see a heartbeat, yet you've already seen that! I know it's VERY hard not to worry yourself sick, but I would say a heartbeat trumps any blood test at this point.
Hugs and belly pats,
