So scared ...

I need some advice . I asked for an early ultrasound at 5 weeks to see baby as I had a missed misscarage a year ago and I'm constantly worried. Well this week I'm almost 8 weeks 7.6 days and I am not really sick at all anymore yeah one throw up in the morning still but I was at about 6 before and now I'm at hardly one time a day. my breasts aren't as sore and I'm starting to panic.. could it just be that my symptoms are just fluctuating. still waiting to hear for an ultrasound appointment 😑 I don't understand how so many people get to see their baby so early and when I request one I don't get it... need some comforting words..
