Can't stop worrying!

Samara
After miscarrying in June quite early on I fell pregnant straight after I went for my first scan yesterday at 5 weeks as she estimated by the size of the sac but all you could see is the sac and at around 4 weeks I was feeling nausea and I don't anymore.. I'm so worried it's a missed miscarriage 😩 
I have a doctors appointment today so I hope to god she give me reassurance and I may ask for another blood test to make sure my levels are going up because I can't wait another 2 weeks for another scan to know!
