Hi guys,

Just wondering for anyone who has done letrozole semi natural cycle -what did cycle timing look like? What cycle days did you take letrozole, what cycle day was lining check, what cycle days did did ovulation and transfer fall? Mine will be a frozen day 6 blast transfer. Thanks! I've always done medicated cycles with estrace but have got fluid in uterus last two fets so this is the plan to avoid fluid! Fingers crossed.

Also did you trigger ovulation or did it happen naturally?

I did for my FET. I took letrazole 2.5mg days 3-7. In my case I had no lining check or monitoring before ovulation. I just let them know when ovulation happened and we transferred a blast 5 days later. It was successful.
I do think that clinics typically monitor with ultrasound and bloodwork prior to ovulation, but in my case the letrazole caused me to ovulate much earlier than anticipated so I never had a chance to do any monitoring. I actually had to put my foot down and insist I had ovulated as at my ultrasound the RE told me it would be awhile yet (all my follicles were small...well duh my dominant follicle was already gone!). I demanded bloodwork to test my progesterone to prove to them I'd ovulated and sure enough I had .

All the best.

Hi ndo_nwaiting. I have done 2 natural fet with letrozole. The first cycle we did in February(failed) and now this cycle that we did in April and got a bfp!

The February cycle, I took the letrozole starting on cycle day 3 for five days. Ultrasound was done on cycle day 12 and bloodwork to monitor for an LH surge that day as well. I did more bloodwork on cycle day 13 where they determined that I was surging so booked the fet according to the age of the embryo.

My April cycle was the same with the letrozole, bloodwork and us on cycle day 12. I surged a day earlier than in my February cycle, and fet was booked. If you have any questions feel free to give me a shout.

I did not need a trigger shot to ovulate.

Thanks ladies! That's so helpful as I'm trying to plan my fet around a work event I have to attend so great to know a bit more re timing:)

[ndo_inwaiting]

Did either of you ladies take bcp the month before letrozole natural cycle? I need to take bcp (and some extra) for timing around a work event but wondering if this is optimal.

[Watermelon]

No. Being on an ocp would have been too risky for me as I needed this to be a natural cycle and wanted things as regular as possible. For some women it can take a few months before their cycles regulate again after ocps and since the whole idea of a natural cycle is to ovulate I personally wouldn't want to mess with my hormones at all and risk that not happening.

Thanks watermelon. I think I need to do the bcp for date planning in order to be able to transfer in June but if things don't look good I guess I can always cancel. hopefully the letrozole will give my body the jumpstart after the pill.
