bel2466 - my blood test came back with my oestrogen still low (389), so O is still a couple of days away. Having a followup BT and scan on Wednesday. Feeling weird that I have such a large follie, but low on the oestrogen side. Also wondering if that means I'll have other follies ready to pop by O time as well! (Had a couple on my right ovary measuring 11-14mm).
I'm not well versed with the when of the FETs, but assuming it would have to line up with whatever cycle you're on? I'm thinking if the Letrozole gives you a shorter cycle, then maybe around CD19-21! Eep! Good luck!!!!
