Despite breakup rumors, Rob Kardashian and Blac Chyna are still very much together, but that doesn't mean it's all been smooth sailing for the Rob & Chyna stars.
"Rob and Chyna are not in a great place," a source tells PEOPLE. "They are always up and down, but they went through a very rough patch as recently as last week. They weren't speaking, or even texting."
According to the source, "It doesn't bode well for their relationship, especially considering the baby is coming so soon. They're not broken up, but it's not a healthy relationship at all."
Kardashian, who is expecting his first child with fiancée this fall, found himself in the middle of yet another social media frenzy after his Twitter account tweeted out the personal cell phone number of his youngest sister Kylie Jenner. After releasing the Keeping Up with the Kardashians star's digits, a third tweet was posted: "Didn't invite the Mother of my child to a baby shower you all were trying to throw for me ‼? You all must have lost your damn minds."
On the most recent episode of Rob & Chyna, Kardashian took some heat from Chyna's mother, Tokyo Toni, after the topic of marriage was brought up.
"You gotta stop what you're doing," Tokyo Toni told Kardashian, 29, with tears in her eyes. "[Chyna] don't need a baby she needs [you to be] a father ... You can't do what you're doing. You're going to ruin it."

Though Kardashian admits that him and Chyna, 28, need to work some things out before they can focus on a wedding, he is "very excited" about the arrival of their little girl.
"His family is sure he will be a great dad," a source tells PEOPLE. "They do agree that for the baby's sake, Rob and Chyna need to find a way to get along better."
