My period is a week late and there has been not a single sight of blood at all since my last period that was over a month ago. I've been pregnant before but miscarried, I feel as if I am pregnant right now. I've been really emotional more like bipolar. My appetite has been on and off also, one day I feel like eating others I don't. I took a test yesterday and it said negative as I expected because I feel like it's too early. Any comments or suggestions in what I should do or when to take another test?
