Hi I referred to my own records last year and during CD9, my biggest was 12 and smallest 9. However I started my pergovaris earlier when I had the issue. However I stim longer like 14-15 days. Hope yours will catch up soon.Im on CD9, its my first ivf. Was given pergoveris (it stings! ) starting from today becos gonal-f alone has no effect on my hormones and follicle size. Is this common? Am i still on time/track for my ivf? My biggest follicle is 8mm as of today..
