I took a pregnancy test a while ago and it came out negative but for a week now I have been experiencing some cramping on and off, and I have been hungary a lot more now; I eat like 7 times a day now and I usually eat like 3 times a day, plus the other day I felt sick and today I had a soar throat this morning and now I feel sick again. My fiancé thinks that it could be my period starting soon but I'm not to sure. What could this mean?
