I felt first movement at 13w3d. I thought I was crazy but I've been feeling the same feelings ever since then, just stronger. She's been giving me definite kicks since maybe 16 weeks, ones that are so hard I sometimes jump from being startled haha.
With my first pregnancy I was about 17 weeks with my current I was 16 weeks for movement. Showing depends on the person. Typically they say with your first you start showing between 12-16 weeks. I wasn't noticeably showing until I was about 25ish weeks.
