So I've used this a couple times now, and I'm curious to know if/when you ovulated on it?

(I'm using it alongside a Frozen IVF transfer, not for timed intercourse, but still need to O for progesterone reasons)

*First time - O'd day 22.
*Second time - O'd day 17.
*Third time - No O, huge ovarian cyst.
*This time - no idea!

When did it work for you? And do you ovulate naturally, or not at all, without meds?
