Please help!

I have had 3 ultrasounds where I have seen a healthy heart beat last one being 8 weeks 5 days. I’m 10 week 3 days today and have a appointment tomorrow. But I’m still so worried something is wrong. I have 0 symptoms none at all no round ligament pain my stomach is still small. I just don’t feel pregnant it’s been like this the whole pregnancy so far. There are no signs something is wrong. This is my 3rd pregnancy first I have a healthy 6 year old the second ended in a blighted ovum. And now this pregnancy. How do I stop worrying and just start to enjoy this pregnancy?!
