I admire you ladies who do this solo, truly. I went through the IVF rollercoaster too and that plus a pregnancy is just f*&king exhausting.
OP I'm so happy for you, that's great. 2 is better than zero, just tell yourself that!

Also, the further along you get (my opinion) the less you need to worry about chromosome issues because your body would take care of that naturally anyway, and so as the days pass on, I think your odds just keep going down.
As far as your egg retrieval number - that too is impressive. You responded really well to meds. I'm 39 and never had results like that.
