I need some advice on when to announce!

I am due 02/20/20. This is my 5th pregnancy, and the farthest I have ever gotten. I was planning on telling my family next weekend, when I will be 14 weeks. We have been planning this forever. Last night, my aunt announced to us that she is pregnant, and due 2 weeks after I am. My question is, do i still announce? I want to since that's been the plan from the beginning, but I dont want to take away her moment. Is waiting a little over a week to announce my news long enough to wait? I feel like my aunt wouldn't care at all but I'm just trying to be respectful. I know if it was me I wouldn't mind. I was NOT expecting her to tell us all shes pregnant as well, lol! My husband and I have experienced 3 miscarriages and 1 chemical pregnancy within the last 3 years so this is so so so exciting to us. I just dont want to take away from my aunt at all! What do you guys think? Also I should mention! My aunt is only 5 years older than me, we are more like sisters. Our whole family is super tight and close. My entire family knows of our last 3 losses, and all of them have known that my husband and I have been TTC for about a year and a half
