This seems unfair, there should be some contingency plans made for OOT DE patients to allow for a 5 day transfer. At my old clinic, I had elected to transfer two 3 day embies on an FET but when we showed up they did not updated the treatment plan and only thawed one embryo. That was the transfer that I did get the BFP. The first RE that I worked with for OE felt very strongly about 3 day transfers and sometimes did two day transfers b/c she felt the "natural" uterine environment is where embies did best. Sorry for the arguing with your husband. Is your transfer still scheduled for Thursday.
