Did Amber Portwood have her baby?

Amber has not given birth yet, but it could happen very soon.

What's Amber Portwood's due date?

Amber's boyfriend Andrew just couldn't wait to share the news when he found out Amber's rather sentimental due date. "May 13th, Mother's Day," the soon-to-be dad wrote on social media. And the date is even more uncanny given it's close proximity to the mom-of-one's birthday.

"One day before Amber's actual birthday. She was born on Mother's Day 1990. The stars really aligned on this one," Andrew added.

How has Amber's pregnancy been?

She's the first one to admit, it's been rough. Amber recenetly announced that she was diagnosed with gestational diabetes and has been experiencing terrible morning sickness to boot.

"My morning sickness has been getting worse, so I went to the doctor and found out I have gestational diabetes," Amber revealed in a clip for the show. "I feel like I could just like go to sleep right now," she told Andrew. "I need to eat some fruit or something. Maybe my sugar's just low."

"This pregnancy — I don't know if it's because I'm older — has definitely been a lot more rough," she added.

Did Amber Portwood pick out a baby name?

Yes, Amber and Andrew have actually already announced the baby name they picked out for their little boy, James, and Amber exclusively revealed why the baby name is so special to her and Andrew.

"It's Andrew's father's name who passed. Andrew was very close to his father. That's the main reason he got into cinematography — his father and his grandfather," she shared. "He really wanted to honor his father and I thought that was a beautiful thing. I even was thinking of putting my dad's middle name in there, but my brother is named after my dad so we just went with James Andrew Glennon. It means a lot and I love the name."

Who is Amber Portwood's baby daddy?

Amber met Andrew Glennon on the set of Marriage Boot Camp, where he worked behind-the-scenes on the production team. Andrew is a cinematographer from California, who is six years older than Amber. At the time that they met, Amber was doing Marriage Boot Camp with her ex-fiancé Matt Baier but Andrew waited until the couple called things off before putting the moves on his now-girlfriend.

"When I did Boot Camp with Matt, [Andrew] ran the lights or whatever … he was pretty much saying he related to my story," Amber told People. "He sounded very sweet. I want to meet him first off-camera, away from everybody so I can get a feel for him, and kind of see if it’s anything I want to pursue. You never know, we might not ever have anything in common and just be like, 'Okay, it was a good ride for a couple of days.'"
