I Feel Sleepy Alot

It doesn't matter how much sleep I get I wake up and it's just like I haven't been to sleep at all. This is after a good 8 + hours of sleep. This was before I got pregnant, just seems to be more evident now that I am. I have had bags under my eyes constantly. I don't know what's going on. I was anemic some months back, but even then I wasn't feeling this tired.
