Is it weird that I'm 32 and have never been (accidentally) pregnant?

I had a conversation with my sister (who has kids) and she was surprised to learn I'd never had an accidental pregnancy/abortion. I know accidental pregnancies are pretty common in my family (my niece was definitely a surprise) and my mom told me she also had a few abortions. I've also had quite a few coworkers who have been pretty lax about birth control and ended up accidentally pregnant.

However, I didn't think it would be surprising to someone that I've never been pregnant. I always just thought I was pretty diligent with birth control so it was pretty easy to avoid pregnancy. Does everyone else just suck at using birth control or what?
