Confused 🤷‍♀️

Da

So I was looking at perinatology.com at calculations.

First beta at 8dp5dt was 15.

Second beta at 11dp5dt was 42.

Third on is tomorrow 13sp5dt.

There’s a few options to choose but there are two that are confusing me. What’s new lol.

I selected the option of 5-day embryo transfer. It’s showing me as 4 weeks 3 days.

But it says conception date of 9/5/2020. How is that possible if I only had my transfer on 9/10/2020?

My embryos were frozen on 8/11/2020 a month even before my transfer.
