Early baby movement?

A

I’m almost 19 weeks and I don’t know if I’ve felt baby move yet. People talk about “flutters” and I don’t know exactly what that means. I’ve had a couple times where I felt some random pressure and felt a little off for a little bit... is this the same thing? So confused. My MIL seems concerned that I haven’t felt anything. She said she felt flutters with her first pregnancy at 16 weeks.
