scared 😓

i'm 7 weeks today and maybe it's bc i'm a first time momma but i'm so scared that i'm gonna lose the baby. i read so many stories about mamas that lost their angels and it breaks my heart. do any of you guys feel the same way? i also heard that if someone is experiencing a lot of morning sickness or other symptoms that it means the baby is healthy. i hope that's true just so i can have some peace of mind 🙁 any advice? or comforting words?
