Worried about another miscarriage

Has anyone had back to back MISSED miscarriages? I’m pregnant with my rainbow right now. 8 weeks 3 days. But my nausea is subsiding and my boobs aren’t sore although they never have been this pregnancy. Last time I was pregnant I went in for my 13 week check and found out that baby stopped developing at 9+5. My symptoms subsided around 9 weeks also. I keep fearing it happened again but is it really likely to have two missed miscarriages in a row or am I just anxious?? My next appointment is in 2 weeks. We saw a strong heartbeat on our early ultrasound measuring 7+4. I just need reassurance 😭
