Could this be morning sickness?

So this may be the weirdest thing ever...I have never liked chocolate chip cookies. I could have maybe one and I can go years without having another. I have had this craving for them and my SO bought me a pack and I ate the entire thing except a row to myself, of course not in one sitting. But now I am completely sick to my stomach from just eating a few just now. Not sure if I'm preggo or not because I've got negative tests, but this was the weirdest thing to me. I don't usually ever get sick or anything over food unless it's gone bad. I'm a month and 2 weeks late on AF but it's normal for me to go a month without it coming. But I'm still 2 weeks late this month.. Suggestions?
