Nervous about 2nd ultrasound

I had a MMC in July and at my second ultrasound the baby has no heartbeat and had stopped growing days prior to that appointment but at the previous ultrasound baby had a heartbeat and was fine. This time around I had an early scan at 5+5 to confirm everything implanted well and my little one had a heartbeat I have another ultrasound tomorrow and I am so nervous I don’t have reason to believe anything is wrong but I didn’t last time either praying this baby sticks with us till may 😩 if anyone can relate how do you overcome the anxiety of having ultrasounds after a loss?
