Pregnant?!?!? Help please

Betsy
Hello everyone, for the last couple of weeks I've been feeling very VERY hungry, very emotional, moody, pee constantly, have headaches, I feel tired most of the time, etc. I started to guess myself if I was pregnant or not because I got my period last month and it was a normal period. Last week I decided to do a pregnancy test and it came out negative. The thing is that I still have all the symptoms I mentioned above. Has anyone been in a similar situation? Please, help!
