Babies death anniversary coming up

Hi guys I've loss my sweet baby at 10 weeks on January 6th 2015. And I wasn't able to get an ultrasound or even told what my due date was because of lost my baby so quickly. And I was just thinking since the anniversary is coming up on would have loved to know when my baby would have been born. I ask this because when I first found out I was pregnant I used a pregnancy tracking app ( not glow) and I was looking at some emails in an old email account I have and came across emails from the app I used to use they crazy things is the app is still tracking my babies growth. I wanted to cry because the last es email I got from the app is ( your baby is 21 month and 3 weeks I fell to the floor and started to cry. And I did log onto the website to try to find information but it dosent go far back. So I was wondering if yall can trying to help me figure out when my sweet angel would have been born if I hadn't loss my pregnancy. It would really mean a lot to me.

Thanks
