When did you start showing w baby #2 (or #3+)?

This is my second pregnancy and I'm probably about 5 weeks along, but I swear I am starting to bump a little! My pants are already hard to fasten. This is really blowing my mind as I didn't show at all w my first until the second trimester. (And I'm pretty sure it's not bloating.) Did anyone else show waaaaay earlier w second baby? I really feel like this is ridiculous.
