Symptoms vanishing....

I had a miscarraige 4 months ago and am now 8 weeks pregnant. My HCG levels were going up but slowly (although already very high) and us at 6 weeks showed baby and heart beat. I had morning sickness and my boobs were getting warm and sore but now my symptoms are vanishing. Does this mean I'm going to have another miscarraige? 😧 With my 2 healthy pregnancies (1 girl and 1 boy) I was nausea and tired right up to 12 or 13 weeks. We have another scan late this week but I'm soooo scared. I just don't feel pregnant anymore 😢
