Movement can be felt early, especially if it's not your first and/or you're very aware of your body. I only have the one so far, but I felt movement at 13 weeks. Lots of the nurses I work with also felt movement that early with their firsts.
I felt movement early with my first so you’re not delusional at all.
It could be! babies start moving a lot during that time! not visibly but sometimes you can feel it ive heard multiple anecdotes and also once you’re going through your second and so on you start showing and feeling earlier than before!
