Guys Obsessed

So I just started dating this guy literally 24 hours ago and he is already telling me he loves and he is calling me baby and love and i don't know how to handle it because it's not like we knew each other THAT long before we started dating not long enough to love each other. He is freaking me out and i don't know what to do about it! Even a mutual friend we have said he is being kind of crazy. I'm honesty a bit scared at the moment. I don't know if maybe i'm being over dramatic because I have serious PMS right now or what but I can't handle this. I want something like love to grow slowly not just out of the blue because then it's like as if it's not real.
