am 34 years old this year. During my last period, I went to monitor my ovulation. When my period ended 5 days ago, I had an ultrasound and saw a normal developing follicle. At that time, the follicle was about 12 mm in size. After 4 days, I had another ultrasound and saw 4 more follicles. The follicles had distorted edges, the largest one was 23x21mm. I would like to ask the doctor what size of follicle is easy to conceive? Thank you very much.
