my period was six or seven days late. I haven't been feeling wel and I've been craving stuff they usually don't want. I'm in very crabby mood allot and I don't understand why I am. I'm always hungry, I'm always tired, and I'm always dizzy and nauseous. in the beginning I thought I might be pregnant, but when I got my. On day 7 I got scared over how much blood I was losing and how bright red it was. I don't know what's going on and I'm extremely emotional.
