Symptoms at 11 weeks

So I didn't suffer from too much nausea to begin with but I did have cramps throughout. For the past 3 days I've been feeling nothing except a slight lower back pain on the right side. I had a MC in May 2018 so I'm very very nervous. We were 6 weeks then and this baby is healthier as per the doctor but I'm so scared ! We just told our families and I'm vvv nervous now. Next scan is in a week ! I do hope there's a heartbeat and a healthy baby else I don't know how I'll deal !
