Well I assumed that's what it was gearing towards. "How I got pregnant" implies a story about how one got pregnant. You can still do well I'd say if you have a collection of images, such like Blackadder does with their numerous characters; even in that case you're still telling a story just not really writing it out but showing it.
If the goal is to simply have character pictures (ie, no action) and with profiles saying if they're pregnant or not, then I don't think you're going to attract much of an audience outside of people wanting to use your characters for their games/stories.
