So I have been cramping for over a week. My period is due on the 27th. And I have no spotting at all. My boobs have been KILLING me and I work at a restaurant. The second I walk into work I get really nauseous. It's rediculous. And every little smell is getting to me. So I said ok I'm going to test. Well..I don't see anything! What do you think?! What is the next step? Should I wait a few more days and test again?
