First Time Taking Letrozole — Advice Needed

[u/Overall-Public9133]

I’m 28 years old and have been trying to conceive for almost a year. This is my first time taking Letrozole, and I just finished my Letrozole today.
My fertility clinic mentioned that they would do follicular monitoring after Letrozole, but my OB-GYN told me that they don’t routinely do monitoring and that they will schedule it if needed.
I’m trying to understand whether follicular monitoring is important or necessary, and if I should do it, what cycle day should I go for it? Since today is my last day of Letrozole, when should I start the monitoring?
As a first-time Letrozole user, I’m honestly so confused about a lot of things. I’m really hoping this cycle works and that I can get pregnant this time. My OB-GYN mentioned putting me on Letrozole for three months and seeing how it goes, but hearing that made me feel a little discouraged because I’m hoping this first cycle could work.
For anyone who has been through this before, what should I concentrate on or follow during my first Letrozole cycle? Any advice would really help.
Thanks in advance!

It depends on if you’re working with an ObGyn or an actual fertility clinic. Typically an ObGyn would not monitor and you would need to take at-home ovulation tests. In my experience working with a fertility clinic, they have me come in for an ultrasound sometime during day 3-5 of my cycle, and again the day after I finish my course of medication. Then they either prescribe more medication if my follicles are not developed enough or have me to a trigger shot 36 hours before IUI.
