Question for all my angel baby mamas out there!

KIND COMMENTS ONLY PLEASE.

This may be confusing or silly. This is for all the mamas that lost their babies very early. such as chemical pregnancies.

But what date did you use as your child’s birthdate/birthday??

The day you found out you were pregnant?

Your due date?

I found out I was pregnant (faint lines so I thought i caught it early) and then a couple days later decided to test again and they just slowly disappeared. So in this case. would I use the date i found out i was expecting or my estimated due date?
