Feeling baby kick???

Since around 13 weeks I’ve been feeling flutters and I know it’s baby, because it’s a different feeling unlike anything I’ve felt before. I’m 18 weeks tomorrow and I think I just felt baby move/kick. It made me jump a little when it happened and kind of took my breath away because I’ve never felt anything like it ever, like a strong feeling of something moving or kicking inside me. Could this be baby? I feel like it’s too early to feel something like that but I’m almost positive it was my baby!
