Movements

So I've been feeling baby girl move since week 14 (this is my second) but after my first and only ultrasound at 18 weeks 1 day when we found out the gender she was moving like crazy and it was more noticeable! But maybe a few days to a week later I noticed she wasn't moving as much (like WAY less!) I was just wondering have any of you experienced this? Is it normal? Should I go to the doc? I'm just trying not to stress about it but honestly it's really concerning... 😥
