Letrozole monitoring timeline

Abby • Married💍 TTC baby #1 🤰🏼

Hey y’all! I’m about to start Letrozole. I know I go in between CD2-4 for an ultrasound and bloodwork. But then what’s after that? When do I go back for the follicle check and how many times do I go back in one cycle? If anyone can share their experiences that would be great. I’m also taking a trigger shot and progesterone vaginal caps so if anyone also has insight on that! Thanks!
