Terrified!

Cass
Someone please tell me this is normal, I'm 8w 3day and I got an early scan at 7w 2 days and I saw the heart beat and was over the moon, honestly thought I couldn't be more in love, but now I'm getting worried as all my symptoms of pregnancy have gone and I don't get my app with the midwife for another week and my next scan for another month! 
Is it normal for all symptoms to disappear?
