10 weeks and extremely nervous for 1st scan

Ashley
I'm 10 weeks and I have a second scan on Monday. I'm an extremely nervous thinking something will go wrong. I already see baby and heartbeat at 5w6d but since having a miscarriage in December at 6 weeks I can't seem to get rid of the nervousness? I've had symptoms including morning sickness and or nausea all day, sore boobs, fatigue and always hungry. Looking for positive advice on what you think
