Baby movement?

Amanda โ€ข Love being a boy mom, now waiting on baby #2 in October! 1 loss '15, 1 ๐ŸŒˆ๐Ÿ‘ถ๐Ÿผ๐Ÿ’™ '16, ๐Ÿ‘ถ๐Ÿผ๐Ÿ’™ '17!
So I am 17 weeks and I think I can feel the baby move but I'm not sure if that's what it really is. Sometimes it feels like a pressing from the inside (same as if I was poking from the outside very gently, just internally). Other times it feels like a bubble growing and shrinking or a hand opening and closing (sorry best description I can give). This is my second pregnancy but the first I've been able to carry this long so I'd love some input! It is in the right place for the baby though.ย
