6 week 3 days ultrasound tomorrow- history of MMC- terrified

Hi all,

I had a missed miscarriage that was discovered at my 12-week ultrasound the end of November. Grateful to have become pregnant again in January, my doctor would like to be pro-active and do an early ultrasound tomorrow at 6 weeks, 3 days. I am so nervous I can hear my OWN heartbeat. I know there may or may not be a detectable heartbeat at this point, but I am curious to hear about other women’s experiences at 6 week ultrasounds; any calming words or tips are also welcome 💕💗✌🏼
