Baby’s due date/first birthday coming up, am I being too extra?

I lost my first baby in August of 2023. Her due date was April 4th of 2024. April 4th is coming up and I'm wondering if I should count that as what would've been her first birthday.

I want to get a cupcake and light a candle to "celebrate" what could've been, but im afraid I'm being too extra or making a big deal out of it. I also wanted to make a Facebook post to remember what would've been her first birthday; but I'm worried people will think I'm just doing it for sympathy. I miss her so much, and I just don't want my baby to be forgotten.
