18 weeks and barely feeling my baby girl’s kicks 😞

Ta

I was feeling her kicks very clearly between 16-17 weeks, but now with 18 weeks and 3 days, I barely feel her! Last Friday I went to my obstetrician’s office and we saw my girl on the ultrasound, she was totally fine and my doctor told me that she just changed her position, but I’m still freaking out thinking there is something wrong!! Did anyone else go through this? I’m so worried! Today she’s so quiet, I don’t feel her, only sometimes...
