Update: Day 1 past retrieval

Ta
Lab just called. Retrieved 3 eggs yesterday, one didn't fertilize, one did but was deemed abnormal, so we only have 1 embryo going. If it makes it to Day 3, we'll transfer on Thursday.
This was IVF#2 and we're TTC#1 = 37 days total doing injections, and all I have to show for it is this one Day 1 embryo. We have none from our previous cycle and I don't even know if this little one will make it to Day3 transfer, implantation, full-term pregnancy, be healthy, etc. 
My husband is already talking about doing more IVF cycles (as we want at least 2 childern) and I just feel like walking into the ocean. Am waiting for this numbness to pass so I can start crying. I just feel so sad & low.
