We're not gonna lie ... we don't think anyone thinks Sofia Richie is pregnant other than our editor who captioned our pix that way. In fact, looking at the 19-year-old's abs, we don't think even HE thinks she's pregnant -- but it sure makes for a good headline, doesn't it!

Sofia and boyfriend Scott Disick did go to the urgent care clinic Saturday, but seriously ... who goes to an urgent care in Malibu if they think they're pregnant? No one! And what girl who thinks she might be pregnant is strutting around in biker shorts and a bra top with abs like that? No one!

So here's another headline option for these pix ... "Sofia Richie Goes Shopping With Boyfriend Scott Disick In Sexy Sportswear." But would you have read the story?!
