Rocking a bright pink ensemble, Chyna stepped on a scale, which revealed her current weight of 170.8 pounds. "Gains," she captioned the photo, using the red heart and baby emojis.

Chyna hasn't been shy about sharing the details of her pregnancy with her followers. Last month, she also took to the popular app to confess her goal of gaining "100 pounds this pregnancy."

"Imma tear it up, then Imma snap back," she continued. The beauty guru also revealed that she had started at 139 pounds, which means she's gained approximately 31.8 pounds since discovering she was pregnant with her second child. (Chyna is also mother to a 3-year-old son, King Cairo, whom she shares with her ex-fiancé, Tyga.)

Kardashian also made an appearance in her Snapchats after taking a brief break from the app. "Rob, I've been missin' you on my Snap and so has everybody else," Chyna said in one of her videos.

Playing with the app's new bread filter, the 29-year-old soon-to-be dad gushed over an exciting moment the two experienced earlier in the day.

"So, today I felt my baby move," he said in a video posted to Chyna's Snapchat and Instagram accounts.

The pair also spent some time with Chyna's parents, which she documented via social media. "My mommy and daddy," she captioned a pic of Kardashian with his arms wrapped around her and her family.

At one point, Kardashian adorably picked his future wife up as she wrapped her arms tightly around him and flashed a smile. The cute moment was perfectly captured on Chyna's cell phone by her parents.

Kardashian also took to Snapchat to share a video of his cheery girl rubbing her burgeoning belly.
