After how many hours of injecting lupride does follicle ruptures

On 14 day of follicular study my my follicle size was 1.8x1.7 n Endometrial thickening was 7mm,
on 16 day size was 8x2.2 n endo 9mm. My doc told the size of follicle is good n she injected LUPRIDE 1mg. Was that size ok to give injection or we should have waited for some more time and how many hours does it take to rupture that follicle after injecting and what precations should I take.
Thank You

It would be very foolish to use the Internet to get a second medical opinion. If you have reason to doubt your doctor, see a second doctor.
