Hazel, don't panic, there will be extra, i.e. although last 30 days but there should be surplus, similar to the gonal F pen, 900 IU but after i inject all, the nurse still manage to extract 75iu from the pen.
I have just checked the IVF instruction, it mentioned that for emergency go 24 hrs to see a doctor. You want to make a trip down?
Don't stressed out now since you are doing ER on Tuesday
