6 AP classes, A's and B's?

I just got A's and B's the past marking period.. I have 6 ap classes (which is all of them) and thankfully only the semester counts towards my GPA (in june). Do you think getting 2 B's means that I should have taken less AP's? Are my grades even anything to be proud of? I'm not bragging or anything, but my parents scoffed at my grades so I'm confused..
