I had my period a little late, which is nothing new because I am sometimes late when I'm stressed. But this period was different. Normally I have to use the super plus tampons and change them every two hours because they are overflowing. My last one it was like it just leaked over the edge but every time I went to change it wasn't full it was like a quarter to a half full. Normally my first day is my heaviest and it wasn't. It was a very light period. Now I am having hunger pangs like every couple of hours and I eat good meals that should last me until the next meal time but it doesnt. I took a pregnancy test right before I started and it came back negative. I don't know what to think of this...should I take another test? can anyone help me out?
