6 weeks pregnant

After a scare with my first ultrasound because we saw nothing but a sac (abdominal ultrasound) , found a new OBGYN whom did a transvaginal ultrasound and I finally saw my little one ❤️ thought I was 8 weeks but measured to be 6ish weeks, no heart beat yet / faint heart beat so have to wait another week to see if the baby is developing good, so anxious but excited hoping all goes well from here first time mom🙏🏼❤️ anyone else had this situation happen? I’m getting lots of blood tests done to be sure nothings wrong
