My cat is acting weird?

My cat is acting weird she is pregnant and she is almost 8 weeks along. She is laying down a lot and she does eat a little but she is refusing to eat sometimes and she is acting restless and like she is rolling around a lot like she cant find a conforable place to lay. And she is licking every where her belly and by her thang. Im getting her spayed after this litter. Is she going to give birth or not?
