First ultrasound!

Shellie • 29 years old. Mother to 7 yr old twin girls and 3 yr old boy. Married 9 years. Pregnant with our rainbow baby!
Had my first ultrasound today. Was so worried there wasn't going to be a heartbeat. Having my 2 previous MC it is hard to not be scared. Well our little jelly bean is doing great. Heartbeat is 164 and measuring 7w 3d but dr said he will keep it at what LMP says, which is 7w 5d. So due date of March 25th!! So excited for our sticky bun!
