Femara Dosage HELP!

My doctor said to take

Day 1 = 1 pill

Day 2 = 2 pills

Day 3 = 3 pills

Day 4 = 4 pills

Day 5 = 5 pills

15 pills in 1 week, 2.5 mg each it all equals to 37.5mg

Starting at cd 3

I feel like I’m the only on on this dosage. Why so much?

Currently on cd 1 on a new cycle (2nd cycle on femara)
