Letrozole round 3 HELP

Hello, I’m currently on my 3rd round of letrozole. I took my first round 3 weeks ago, second round 2 weeks ago, and 3 round this week. I grew 3 follicles, one is 10mm, this Tuesday I have another appointment to see the promising follicle grew more. How is the letrozole being subscribed to you ladies? Having a lot of bone pain, dizziness, and fatigue. I’m staying positive and praying for my miracle.
