Kim Kardashian West is squeezing everything she can out of her pregnancy bod.
The 34-year-old reality star posted a group of bikini selfies, flaunting a shocking amount of cleavage on Friday. The photos were in honor of Flashback Friday, as they were originally taken during her recent St. Barts vacation with her family, including her mother Kris Jenner, as well as sisters Kourtney and Khloe.

"Kisses from St. Barth's," Kim captioned one pic.
The actress and model is expecting her second child with husband Kanye West later this year. In an interview with C magazine's Amanda de Cadenet, she revealed how difficult it was for her to get pregnant a second time.
"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," she told the magazine. "I was trying everything: I did acupuncture and got a nutritionist to eat healthier, thinking that was an issue."

Kim thinks that a condition called placenta accreta is what made it harder for her to conceive again. Placenta accreta reportedly occurs when parts of the placenta grow too deeply into the uterine wall. Kim also believes this could potentially ruin her chances of conceiving a third time.
"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," Kim revealed. "I think we're just gonna go day by day, see how overwhelming it is, and see how the delivery goes."
