Is this the baby moving?

I’m 19W5D with my first baby. I’m plus size with an anterior placenta. I think I’ve been feeling my baby move, but I’m not sure. Everyone told me to look out for butterfly feelings or gas bubbles, but it doesn’t feel like that at all. It feels like there is a trampoline in my stomach and she’s jumping up and down, landing on my uterus. It feels like big plumping or dropping sensations. I’m assuming this is her doing somersaults or something like that in there. There’s also this other feeling that’s hard to explain. It’s like it feels like nothing, like I don’t really feel anything, but it just feels like somethings moving. It’s weird, it’s like i don’t feel anything but i can feel movement! I feel nothing but I feel everything at the same time!

Anybody else experience things like this? I’m hoping this is it, I’m desperate to feel my babygirl!
