Still not good news. We are monitoring 3 things. HCG is what the embryo/placenta releases. At this point, it should be at least 50. It went from 9 on Friday to 17 today. It should double within 48 hours, and although it did do that, it is still alarmingly low. My progesterone went down from 6.9 to 2.5, which is not a good sign. The only good thing is that I can take medicine to improve it. My estradiol went up 70 to 174, which is good, but is probably caused by the fact that I already up'ed my dose of estradiol the other day. Unfortunately, there is nothing I can do to raise the HCG, and that is the most important number. That is all up to whatever is happening inside. I will have to wait until Tuesday to have another blood test. I haven't been poas and I'm not sure if I will or not. The levels are so low that the darkness of the line is greatly effected by what I have to eat or drink and I need to drink with the d*^m cough! At this point, my chances are slim...but not none. Not great odds. Going between hopeful and realistic. Sigh.
