Can't wait!

AF is suppose to be here in 3 days. I want to test but I don't want it to be to early. My lower tummy is hard, I have nausea, cravings, I can't sleep on my tummy anymore, all my senses are going crazy, I'm having vivid sex dreams, and I'm horny all the time. Could I be pregnant? Or I'm I just wantinh to be pregnant and mind tricking myself.
