First time mom and so paranoid

Hey guys.

I’m a first time mom. I’m 5 weeks and 4 days currently.

I haven’t heard of blighted ovum before the last few days where I’ve been reading about it. I’m like deathly afraid to go to my first appointment in two weeks and have them say there’s no heartbeat or nothing developed.

So, what’s your experience? Are there any warning signs? What are the chances of that being the case? I’m so scared and I can’t get it off my mind - it’s starting to completely consume my pregnancy because I feel like I can’t get excited in fear something goes wrong.

I just need some reassurance of some kind.
