I did a modified natural FET at CCRM this fall. I took Letrozole CD3-CD8. I had my first monitoring at CD9 or 10. I had a 15mm follicle at that point so they brought me in daily until it reached 22mm and my estrogen was over 120. That timing made my transfer fall on a Saturday. It was fine. They don’t do fully medicated transfers on the weekends but will do it for transfers based on your cycle.

It's never been clear to me what a modified natural FET vs. natural FET actually is, but I did one in June this at CCRM. My only drug before transfer was a trigger shot. My transfer was mid-week, but nobody said anything before or during about GonalF and cetrotide. After transfer I was on Prometrium and Estrace.

Are there any clinics in the area that transfer over the weekend/allow true natural FETs? I have done multiple modified natural FETs at Shady Grove, but they told me they don't do weekend transfers so you have to take a few days of meds to postpone ovulation if it looks like you are going to ovulate over the weekend. This means you have to have Gonal F and cetrotide on hand in case you need them, which adds a huge expense to the transfer for those of us with no insurance coverage who don't happen to have any leftover meds from retrieval.

I am going a modified natural fet right now. I did baseline monitoring day 2 and then monitoring three other days (cycle days 9, 12, 13). Triggered on day 13, started progesterone suppositories the following day, transfer will be on day 19.

Has anyone done a modified natural FET and if so would you mind sharing your experience? (how long the cycle took, results, etc.)
