I know this is a stupid question but enlighten me haha

I'm freaking out about my gender scan next week. I'm just so terrified they're going to say "he/she stopped growing" or "measuring only 14 weeks" or just something horrible ya know? I've had 3 healthy ultrasounds already, every appointment has been great. I consistently find the baby's heart beat with my at home Doppler. Everything seems perfectly fine. But after a miscarriage in April I can't help but worry. The question here is... The fact that the heart beat has gotten louder and stronger each week is a good sign, right? I know I know...try not to stress. And believe me, I'm taking each day as a blessing. I just can't help but worry 😢
