Baby Drama! Blac Chyna & Rob Kardashian Struggle With Serious Pregnancy Complications

Blac Chyna and Rob Kardashian are looking forward to the premiere of their new reality show in September, but RadarOnline.com has exclusively learned the couple's just as anxious to give birth to their baby — but not for the reasons anyone thinks!

"Blac Chyna is going through hell as she enters the final trimester of her pregnancy," an insider revealed. "She never knew it would be this uncomfortable and is really struggling."

While "the never-ending nausea, heartburn, cramps and gas are one thing," continued the insider. "Rob and her family are extremely worried — her blood pressure is higher than it should be and isn't helped by her terrible diet."

However, another pregnancy issue is causing more havoc for the expectant mom and dad.

"What's even harder for Chyna are the mood swings," the insider revealed to Radar. "She's all over the place, crying non-stop then flying off the handle for no reason."

The situation has become so unbearable that Chyna, 28, and 29-year-old Kardashian "are looking into having the baby induced ahead of schedule, by C-section."
