Very attached to partner!

Ever since me and my partner have been TTC I have become very clingy and attached to my partner like I hate to be away from him. We live together and we spend pretty much every evening together obviously other than when he has his nights with friends and I do the same. He's just gone off on a weekend do with his friends and we have been TTCing this month and we done it when I was ovulating. I just have found myself more clingy and attached than before, is this normal?
