Worried- 23 weeks and no movement yet!

Hi! I’m pregnant with my third baby, but my two kids now are 13 and 15... I’ve felt absolutely no movement at all, yet an ultrasound at 18 weeks showed the baby moving like crazy. I have an appt in a week but I can’t stop freaking myself out. Can anyone relate?

And when I say no movement I don’t mean lately, I mean at all, the entire pregnancy. Today I’m 22w6d, baby die dec 28th. Any advice or words from people who can relate would really ease my mind!!

Thank you ❤️🙏🏼
