Monday night on Teen Mom OG Season 5 Episode 8, Farrah got into a nasty argument with her mom … what else is new, right?

Meanwhile, Amber found out she was expecting, and Ryan and Mackenzie celebrated a joint bachelor and bachelorette party.

There’s no need to tease that someone is pregnant on Teen Mom: OG, because in this day and age, you already know who it is.

Still, there’s always more to the story that you don’t know, and for Amber Portwood and Andrew Glennon, timing was everything.

On the couple’s Hawaiian vacation, she ended up getting sick right away, immediately and then continuously feeling nauseous.

You know what that means!

Despite the exciting pregnancy test reveal (see video above), it wasn’t all sunshine last night, thanks largely to Andrew’s past.

Amber’s ex, Gary Shirley, started reading things in the news about him, and discussed Amber’s battle with depression issues.

He ultimately relayed this to his wife, Kristina Anderson, saying that as always, it’s all about Leah, his daughter with Amber.

Kristina revealed that the couple told Leah that Amber hadn’t been coming around as much because she was too depressed.

That’s fair if true.

However, Leah later asked Kristina: “If she was too depressed to see me, she wasn’t too depressed to find a new man?”

Meanwhile, Catelynn Lowell decided to get her birth control device out but wanted to keep that a secret from Tyler Baltierra.

Right away, that’s a recipe for disaster.

By the time she turns 30, she hoped to be done having children, she told her mom, and now that she’s 26, the clock’s ticking.

Cate was told by her doctor she needs to drop 15-20 pounds to get healthy, however, plus quit smoking (Tyler already has).

In the world of Farrah Abraham, she decided to take her mother and her father on a family vacation, a very nice sentiment.

At least it was, except for the fact that she neglected to tell her mom that her dad and his girlfriend would also be on hand.

Naturally, the moment Debra showed up and ran into Farrah, Sophia, Michael and his girlfriend, Amy, was beyond awkward.

Nevertheless, they somehow persevered through that and were having a cordial time with one another. Shocking, we know.

Later, though, Debra brought up Farrah’s ex-lover Simon Saran in front of Sophia, and Farrah proceded to flip her actual s–t.

As soon as Sophia was out of earshot, Farrah called Debra “an evil bitch” and said she didn’t want to speak to her anymore.

At least Soph wasn’t there for that?

Last but not least, Mackenzie Standifier and Ryan Edwards jetted off to Las Vegas for their bachelor and bachelorette parties.

There, Standifer broke down talking about her bizarre parking lot wedding to Ryan last spring where only his parents came.

Those were dark times, indeed.

Mackenzie added that at one point, she didn’t even know if he’d be alive, so thinking about a future with him seemed bleak.

Ryan, for his part, confided that he’s not sure if he’s ready for another child … making reports of them trying for a baby feel troubling.

Standifer mentioned that she invited his ex, Maci Bookout, and her husband, Taylor McKinney, to the wedding. But did she?

The invite came to “Maci Bookout” and Bentley … as in her maiden name, and without Taylor’s name appearing anywhere.

Bookout planned to bring him anyway, so we’ll see when we watch Teen Mom OG online next week if that caused any drama.

Feels like a good bet.
