Hi HappyPeanuts, thanks for sharing. I think it is a bit different for SGH, I am supposed to call them on my CD 1, then go for 1st scan either on CD 2, 3 or 4, then 2nd scan will be on CD9 to determine the lining and the follicle size. Then on CD 14, 15 & 16, will take blood test in the 3 days morning and afternoon to check for ovulation and decide on ET day. If ET happens to be on Sunday or PH, they would still go ahead for the ET

which is good , at least would not missed the ovulation timing. For my 2nd fresh, I had my ET done on a Sunday

.
I think the xiong part is the 3 days where we need to go and take blood test in the morning and afternoon, but no choice, guess they wanna keep a close eye on the ovulation. By the way, they said no need to use opk to track LH surge cos the blood test is sufficient liao.
Hmm, can share why is the natural will give our embies the best chance? U mean medicated is not so good environment for embies?
