Hi mothi!
I'm assuming you're using cm and not mm...and if so, the measurements sound pretty normal for CD11. You basically have four follicles between 10.5 and 14 mm. The follicles tend to grow about 1 mm a day in the beginning and about 2 mm a day closer towards ovulation. In general, 18 or more is considered mature. Best of luck!
a follicle is considered good size more than 16mm.Today is my 10 day and i have follicles more than 15mm but i'm on injections.Yours are not in the mature size yet.
