My best friend just suddenly disappeared

So we have been friends since elementary school, we are now in our 20s.

We both are brutally honest with eachother and have been through EVERYTHING.

We have gotten into fights of course, what friends don’t, and have gone a month without talking, just cause we need a break.

She is currently 14 weeks pregnant and works in a nursing home. She took leave when the virus started and recently started back up.

She told me a coworker took maternity leave and she was wondering if it was a bad idea that she didn’t do the same.

I told her truthfully that yeah, I kinda thought it was. She got defensive, which is kinda normal, and we ended up dropping the conversation. Later that day I sent her a funny video on TikTok about best friends and how no one understands you like one. A few hours later she blocked me on Snapchat, yes blocked! And will barely answer my texts.

My mom said it’s my fault and the video somehow insulted her, “you made her think she was gonna be a bad mom”

Now I have friends who, after getting pregnant, kinda went... coo-coo. Very very emotional and one girl actually lost all her friends for a few years.

Anyway, what can I do? We have never unadded or blocked eachother, ever, and I’m kinda panicked. Is this “normal”?

*and I know I probably did something wrong, I have a habit of accidentally saying the wrong stuff. But I just wanna know how to fix this
