Kinda afraid to go to my appoinment...

So i was finally able to make a obgyn appoinment for this pregancy. But now im almost to freaked out to go. So many women have said that when they go doctors say no heart beat and they miscarried ... But they had no spotting no sympotoms... Due to my last period im past 7 weeks closer to 8. So there should be one... But i dont think i could handle going in there and hearing news like that... :(
