Kourtney Kardashian is now the LEAST lady-lumpalicious of all the Kardashian-Jenner clan!

Kim, Kris and Kourtney hit up Erewhon grocery store with Kourt's son Mason, on Thursday -- dressed to the nines, of course! Kim showed off her baby bump in a tight black dress and Kris wore a matching get-up that put her derriere on FULL display. Like mother, like daughter!

And while Kim is certainly celebrating the fact Kanye was able to put another angel in her ultrasound, she chatted with C Magazine recently about her fertility struggles and how IVF took the fun out of conceiving their second child.
    “I had so many complications. I had this condition called placenta accreta. There were a couple little operations to fix all that, so that created a little hole in my uterus, which I think made it really tough to get pregnant again. It was a long road. I would go to the doctor in Beverly Hills every day at five in the morning to get tested to see if I was ovulating.”

So does this mean that two kids will be it? Sounds like it...
    “They think I’ll have placenta accreta again, so if the placenta grows a little bit deeper than it did last time, then they are prepared to have my uterus removed, which is a little scary for me. I think we’re just gonna go day by day, see how overwhelming it is, and see how the delivery goes.”

Still, this pregnancy sounds a little bit better than the last...
    “I also feel lucky that, as of right now, I don’t feel like I’m gonna get preeclampsia again, which last time [contributed to] not only the weight, but also the swelling that everyone would make fun of, not understanding that I had this condition. It was the worst! I couldn’t help it, and everyone would say, ‘She can’t stop eating.’ I delivered at 180, and they were like, ‘She’s 210 pounds. She’s getting dumped because she’s too fat,’ and all these ridiculous stories. It really took a toll after the fact, when I was losing weight.”
