Is something wrong with me? Or is this normal 💤

So I've never ever been a napper in my life. I always feel like I'm wasting part of the day or something. 
Now that I'm almost 33 weeks I sleep at least 9 hours a night and then take two one hour naps when I get a chance😯 Does this mean somethings wrong? Or is it normal to just be really tired during pregnancy? I'm not depressed or something right?Â
