Help! I need some thoughts! Am I just overthinking?

My ex and I recently decided to split. I am 13 weeks pregnant as well.

I had recently tagged him in a post announcing we are having a baby on the way! However, I just noticed it does not show up on his tag page on his ig. I honestly feel like he’s already hiding our daughter and I have this feeling I was always right about that there’s someone on his ig that he always wanted to think he was single. Or he’s already talking to someone new and doesn’t want them to find out. I would like to have this conversation with him and ask him but I already know I’ll be called toxic and he’ll get very angry with me. Am I being toxic or just overthinking?
