How do you calculate DPO with a FET?

I did a 5dt, so would it be 5 days plus how many days ago I had the transfer? Confusing!

If your FET was on February 1, today you would be 11dp5dt or 16 dpo.

Ok, thats how I was thinking too. Thanks!

Are you sure it wasn't a 6 day FET? They thaw the embryo a day before your transfer usually and allow it to develop for a day (to make sure all's well I think). If you froze a 5 day embryo, you'd have transferred a 6 day embryo. I think it's unusual to freeze on day 4, making it unlikely you transferred a day 5 embie.

No, we had two five day embryos frozen. We ended up have three AA blasts on transfer day, but wanted to transfer one.

My lab thaws them the morning of...not sure how many hours, etc ahead of time but pretty positive its same day.

your numbers are all wrong - they defrost a few hours before, and they don't freeze on 4 - they freeze on 5

Could you please let me know what the abbreviations mean? Thank you.

dpo = days past ovulation; dpt = days past transfer; FET = frozen embryo transfer
