Just received an invoice from the lab today saying three items were tested: ahCG,AFP uE3. But when I called my doctor for the results she told me two numbers only: 1.43 and 0.69. Could those be the free -hCG MoM and PAPP-A numbers you ladies are talking about? Are these more of a girl or boy indication? I am so confused now...

They say a PAPP-A under 1 which yours is 0.69 is a boy how true that is I dont know and with the hgc MOM I dont know anything I know mine was 3.07 but I cant find anything on it

which delves into things at greater length but, in summary, the gist is as you say, that looking at trends from certain NT results, a PAPP-A lower than 1 often points to boy and a higher hcg MOM correlates more with girls (the boy average is 1.0 and the girl average is 1.185).  Your 3.07 is phenomenal and suggests girl. 

As with everything it seems, there are outliers, HOWEVER, what I have seen JUST from the data shared on the aforementioned thread (pretty limited data set):
