7 weeks and 4 Days, how do I know my baby is okay?

Ty • - 💕

Hello everyone! I’m currently 7 weeks and 4 Days with my first! I had transvaginal scans at 6 weeks and my little bean was doing fine and had a strong heartbeat. I’m 22 years old. No history of miscarriage, and in pretty good health BUT I’m about to worry myself crazy!! How do I know he/she is okay in there?? I’m so anxious for my next appointment at 9 weeks to check on my baby! Anyone else a worry wart like me!? Lol
