Fearful and obsessed with loss

After a molar pregnancy last fall and a complete vanishing of symptoms, I can't help but obsess that we have already lost this one. Sore boobs and fatigue has subsided. Not nauseous. Feel totally normal. Ultrasound is on Friday. Considering telling a friend just to have someone to talk to about it. (Husband just encourages me not to think about it til we know - good luck w that.)

We desperately want this baby. Im so scared of my appt on Friday (two days before my bday, no less) and hearing we lost it. :(
