Confused!

Nikki

My period was due yesterday and it still hasn’t came yet! I took a test yesterday and it said not pregnant it was a digital! I usually get cramps for a day or two before period I haven’t had any! For the last week I can’t get enough to drink and I have been eating gardettos like crazy lol i have so been sick to my stomach off and on for like a week! I’m confused if the digital are really the best to take!

Anyone have advice?
