Cat acting strange before labor?

𝙲𝚊

I’m 39w4d & my cat has been acting very strange with me today. He’s usually very introverted, independent, doesn’t like cuddles but will accept them sometimes if offered & spends most of his days asleep. Today he’s been meowing at me nonstop. Every time he sees me he meows loudly at me & demands that I pet him. He’s never acted this way before & im wondering if maybe it’s a sign? I know it’s silly but I just wonder if anyone else’s cat(s)/dog(s) acted out of character shortly before going into labor?

This is him❤️
