Anyone else have similar worries that ended in good outcomes?

Had my first ultrasound at 6 weeks and baby had a heart beat of 100bpm and my OBGYN didn't look concerned at all. I had an ectopic in June and a miscarriage before that this year so I'm all paranoid. I go for my 8 week ultrasound on Monday morning and just praying baby is still progressing great and is healthy with a strong heartbeat. My fear is they find something wrong and I hope my fears are always wrong🙏
