I don't know what's going on

So my husband and I have been trying to get pregnant for almost two years now. And for some reason this month just feels like it could be the one. I had my period on thanksgiving for 5 days and then two weeks later I got what seemed to be a period but was light and lasted 3 days. This week weird things have been happening. I have been more tired but getting same amount of sleep, I can't stand the smell of certain foods like pizza I took one bite and almost vomit all over the floor. I have had mood swings and I haven't been that hungry. I also seem to have a cold but it's only a stuffynose. When I lay in bed and my husband gets in and moves the bed I feel like I'm going to vomit. Also I have been having weird dreams which seem to always be me being pregnant but I could be going crazy. I took a test yesterday and it came back negative. Period due on Saturday 12/24. What are your thoughts??
