8 weeks today and I get nervous by the week

Hey I miscarried last year in February and found out March 11, 2025 that I was pregnant again. I just made 8 weeks today and had my first appointment doctor said all my blood work was great and they found my baby and I got to hear the heartbeat, it was 171 bpm. This brought so much joy to me because last year I found out extremely earlier and all the hospital kept saying was they didn’t see anything or I may have miscarried. Waited a few weeks went to a free clinic and they found my baby and said it was too early for the heartbeat then I ended up miscarrying weeks later. So them finding the baby and hearing the heartbeat really helped me feel better 🥹 Im just trying not to worry. When will I be out the clear? It’s been so long, my daughter is 20 and my son is turning 14. I was 7 and 5 months when I found out with them 🤦🏽‍♀️
