8dpo BFN! Am I still in?

I don’t know why I do this to myself! 8dpo and I felt the need to test because I am convinced I am pregnant. It sounds really stupid but I was craving milk this morning and that was my only craving with my first pregnancy. I hate milk normally! I’m also lactose intolerant so the sound of milk always irks me! I tested because I wanted freakin milk...ugh! I’m insane! How do you ladies keep your willpower and self control?! I still have a chance, as 8dpo is early...right?
