Congratulations WW!! Love a great natural miracle story - I am o thrilled for you. Enjoy every single moment

Positively - I'm going to preface my answer to your question by saying that everyone has their own opinion on this whole day 3 or day 5 thing... I have a fairly strong opinion but that by no means - means that I am correct. You must always remember that many women have fallen pg from FET's from day 2, 3, 5 and even day 6 transfers...

I had OHSS with my first fresh cycle and then Christmas happened so I had to zit 3 months to do my FET. I did so much obsessive research I turned a bit nutty... I can admit it after talking to my FS, my OB and doing a truck load of research online and through various clinics in Perth - My personal conclusion, for me, was that a day 5 blastie transfer gave us the best chance of falling pg. Why? In really simplistic terms - I figured if the embie made it to day 5 - blastie stage then it had a better chance of 'going on' and continuing to divide.

My FS agreed with this for me on the basis that I had 12 frozen day 3 embryo's. If I had have had less embryos I'm sure he would have pushed a day 3 transfer. He agreed for my first FET on the basis that I agreed to defrost 3 day 3's. What happened next solidified my opinion that for me, I would always transfer a day 5 blastie as my first choice.

So we thawed 3 x day 3 embies. All 3 had the same number of cells and were classified to be of the "same quality" - on day 5, one was a 'beautiful blastie' - (the now twins), the other was a 'good blastie' and the 3rd embie didn't make it to day 3.

So I spent a fair portion of my 2ww thanking my lucky stars that we had taken them to day 5 and not transferred the one that didn't make it to day 5. In hindsight I now think to myself, all great but what if by putting it back in on day 3 it had've survived etc... Aaaaaaaggggghhhhhhhh

What do I believe now? I am a lot more relaxed!! And I have a lot less time to obsess I still choose to do day 5 blastie transfers because that is what is right for me. But this is my last baby and I had and still have a relatively large number of good embryos. Now I am not an embryologist, so i don't know enough about the time lapse filming or how that predicts what your embie is going to do AFTER the thaw. I have always thought you'd only know what would happen by actually thawing - but I could be wrong... I was also influenced by the fact that several of the most highly regard FS in Perth only do blastocyst transfers.... (unless you have done more than 3 cycles without having anything to show at the end of them) - this seems a bit harsh to me. I believe it is my embie so I should be able to choose what stage I want to transfer at, based on the opinion of the embryologist and my FS. As I said at the start many many ladies falling from day 2, 3 and 6 transfers... I think there is a lot more too it than just embie age... Quality for example must be critical?

FET cycle length... Are you doing a natural or medicated cycle? If natural I would think it will be the same as your normal cycle (my first cycle was unmedicated and it was normal length). If medicated - the trigger will determine when you ovulate, and the pessaries will likely prolong your cycle (can take a while for AF to come back for me).

I've done it again!! I'm so sorry!! (embarrassed icon) That's what sitting on the couch all day does to you!

AFM - I POAS today to see if the trigger has left my system. IT has not Very feint positive... I have to say weirdest thing I've ever experienced and I don't like it - a feint line when you know your not pg. It's very odd and I now feel like I have to test every day until the line is totally gone. And then even if I get a real bfp I probably won't believe it until it's confirmed by BT.

Worrywart congratulations again! Your a dearest superstar and I'm so thrilled for you again
