Slow growth in pregnancy

I am 36 weeks pregnant. I went for my midwife appointment today. I didn’t see my usual midwife, she is on holiday. I was seen by a different midwife that I haven’t met before. She measured by belly and told me that there is slow growth for my baby. Basically, she said that my baby’s weight dropped since my last 34 weeks midwife appointment measurement. She told me that she is sending me in for growth scan. My heart literally stopped beating.

I have never been so afraid in my whole life. I hope my baby is fine. Has anyone here experienced something like this? 😩😩😩😩😩😩😩😩😩😩😩
