Help!

Tiffaney
The past few weeks I've experienced short-lived but strong cramps on one side. Lower back aches and pains all the way across. Heightened sense of smell. Hungry all the time. Thirsty all the time. AF isn't due until the 10th. Negative test this morning. Is it too soon to count this cycle out? Is it early symptoms? Am I psych-ing myself out?
