This seems like it would be an obvious answer, but do your RE’s calculate from the date ER or the ET date? All the info on the web looks like ER is the date to use (+2 weeks).
But my doctor said they calculate from the date of transfer, even with a fresh cycle. Which I thought was weird. I know it shouldn’t make all that much difference, but 5 days seems like forever when you’re tiptoeing through the first trimester.
How do your RE’s do it?
