Hi, I am 19 years old and have been having regular periods since I was 12. The last time I had my period was on May 4th and I was expecting it again around June 7th. It's been nine days so far and all I have felt are mild cramps which come and go, a little lower back pain, I have been feeling EXTREMELY hungry which is weird to me and when I do eat after a little while I have to go poop or I'm just hungry again. Also, the day after I was expecting my period I felt like I had gotten it but it was just clear fluid. That has been coming out ever since. I took two pregnancy tests and both say not pregnant. So other than pregnancy...what could it be?

Please answer :!:
