Thanks for writing to us.
On day 12, a follicular size of 8mm size is a small one. usually a mature follicle forms by day 14-16 and measures 16-20MM in size. Since this is your first cycle on fertyl
, you can repeat the same dose for next cycle too and see the response.
I hope this information has been both informative and helpful for you.
