Help!!!

I have been feeling sick for over 2 weeks now. Smells bother me. I can smell anything from a mile away. Foods bother me. If I order something that sounds good it may not taste good, I take a couple bites and feel like I could puke. I'm not eating much becuz I feel instantly full. Very bloated! Yesterday my boobs started to hurt and last night while sleeping I would wake up becuz they would hurt and this morning you can see my veins in my boobs. My nipples feel funny. I have a headache as soon as I wake up and my back hurts. I wake up just as tired as I went to bed the night before. Having hot flashes once and awhile. Sometimes cold I am having cold like symptoms now. I don't know what to do I have taken lots of pregnancy tests all come back negative except one very faint one. And last week Wednesday I even went to the doctor and they did a urine test and it came back negative. I don't know what to do anymore but I know something isn't right! Please glow family help me!
