Did they do another beta after that? My IVF clinic would consider 10.84 to be a positive. But since it went from 7 to 10 in three days, they would have wanted to test again to see what it did next, go up or down.
m,aybe try another round of ivf if you can afford it, look into doing a fertility detox before you start your cycle also do a couple of cycles of acupucture before and during your ivf, acpucture has shown to increase ivf rates, good luck
