how many embryo left?

My obgyne asked: how many embryos do I  left in Hong Kong? She was pushing me to have another embryo transfer. I was speechless. I am worried about post partum flare- ankylosing spondylitis and uveitis. 

Ei, am I fertile? Is this pregnancy a result of pure luck? Will there be a lucky streak? should I be greedy? Can I opt not to use Ivig? I am afraid of antibodies. I had systemic inflammation before ( crp + ) two days after ivig.

I have not given birth yet. But my obgyne has asked how many embryo do I still have in Hong Kong for several times already.
