I am at the beginning stages of fertility care. I have seriously abnormal periods (1 every 7 months). I don't actually do for my consultation until the but I had to have an ultrasound done bc I have a uti and they wanted to rule out cysts. The tech was nice enough to answer some of my folli and lining questions. I dont know what I would do without google!
From what I know, mature follicles are considered 18 mm or more (1.8 cm). Mine were 15 mm when I took my trigger shot but they grow after still. What procedure are you getting ready for? IUI? IVF?
