Opinions?!

Ca
So this may be long but I would like to hear SOMEBODYS opinion .
I was a week late for my period and when it finally came it was only a dark brown for three days. Weird. I thought it was weird so I took a test. BFN. So it has been three days later and I'm waking up in the middle of the night STARVING and wide awake. And when I eat I'm still starving. I could eat the whole fridge and I'm still hungry and usually I sleep 14+ hours without waking up ( I know that's bad ) lol
Should I take another test today ?
