By how much does the uterus lining grow per day and how much per day do follicles grow?

Unclear. A uterine lining grows by less than a millimeter a day during one's follicular phase of the cycle (the first 7-14 days). Not perceptible to the naked eye even if you had an ultrasound every day. Follicles grow on average anywhere from 1-3mm in 24 hours.
