Don’t Feel Pregnant Anymore

I’m trying not to worry too much, but I’m just past 8 weeks and I don’t feel pregnant anymore. I feel zero connection to what’s going on down there, my boobs barely hurt anymore, I only had a tiny bit of nausea before and now that’s gone. I’ve been waiting what seems like forever for my first ultrasound and I still have another week to go before finally having some semblance of relief. Do the disappearing symptoms potentially mean I have a blighted ovum or the baby stopped growing after 5-6 weeks and my body just hasn’t recognize it? I’m seriously panicking and waiting another 8 days to find out for sure is torture.
