My period is a whole week late, I haven't had any spotting or anything at all. I have been using the bathroom more than usual, my vagina looks different, I've been really tired this past week, my stomach feels sick and after I eat I feel like vomiting, my boobs feel heavy and look bigger, I feel nauseous when I when I stand up after sitting for a while, and headaches. But I took three at home test and they came up negative.
