nauseous and hungry

hello me and my husband have only been ttc for two months now got what I thought was my period on the first bled until the 3rd and spotted the 4th and that was it but for the last week I have been really nauseous and hungry also have indegestion bad. today when I was putting some roasts in the crock pot I ended up vomiting just from looking at the raw meat through the package (it was good just bought them) anyway I tested twice and they came back negative so I have some doubts that I'm pregnant. anyway what do yall think??
