Ganirelix - do I need another dose?

Na

Hi.

So I started on Ganirelix on Wednesday and will most likely have the egg retrieval on Monday. When i was at the clinic today, I forgot to ask if I had enough Ganirelix. Only four of them were prescribed so my last dose will be on Saturday at 8PM. Does that sound right in preparation for the Monday retrieval? Do I need another dose for Sunday? I'm a little confused and afraid i might ovulate too early.
