Mom4sure- you are officially diving head first into your BFP! Hope your travels were safe and sending you lots of baby dust.
Tammy- I was on a similar protocol last time (cetrotide instead of ganerilix, but they are similar). My RE is fully supportive of DHEA and had me quit the night prior to trigger so I think you are fine. That ganerilix will slow you right down and you won't ovulate until trigger. No worries lady- sounds like you are right on track for you BFP!
Dallas- are you ready for STIMMING???!!! Congrats on graduating to the next phase.
Ellis- my clinic likes 3dt, but after one fresh and one failed FET, I talked them into the blast. Reason being is that I was really tempted to transfer three but can't risk multiples. In my mind, that is the distinguishing factor. In any cycle you know that some of your embies will take and some won't, but unless you do genetic testing you can't know for sure which ones are genetically capable to go the distance. Going to blast acts as a kind of survival test so you know that you are only transferring the strongest. Naturally the risk is that you don't have enough strong ones to make it. For me, that risk is offset by the lower risk of multiples from transferring too many 3 day embies. Now interestingly enough, for me out of 6 fertilized embies only one made it to blast by day 5 and three were morulae (slow developers). So I am glad I did it because it sort of confirmed for me that we have some embie quality issues. I could have gone through 2 more FETs with the frosties I have from IVF number one to learn that, but I liked knowing how things progressed by day 5. Of course every cycle is different and every woman is different so its really up to you and your RE. I will say that if I had it to do over again I would have gone to a clinic that does 5 day transfers more often. I am sure mine did just fine, but they do it on rare occasions which does make one wonder... its a different process requiring a different culture medium and it just feels like maybe I would have been better off with a more experienced clinic.
All that said, Ironically we ended up transferring three given our concerns about quality on this last try. Now we have four three day embies left and one morula. So now we will be letting those 3 day frosties grow to day 5 and transferring whatever makes it along with the morula. I am so worried about how those embies survive the thaw! Its going to be a stressful cycle...but then again they are ALL stressful cycles.
Baby dust to you!
