I feel... Pregnant! Help me!

So first off, here's my chart thing. Based off the times I had sex, can I be pregnant? I took a test yesterday. BFN. I have symptoms that I've never had before. And still no period ! I don't know what to feel.. I feel nauseous right after I eat. I constantly feel like I have to throw up. I sleep like 13 hours now! And vivid dreams! Oh and my boobs feel kind of tender an so do my nipples.. I just don't want to get my hopes up..
