When Briana DeJesus stopped by her local Planned Parenthood following a drunken one-night stand with her ex, she probably just thought she was exercising an abundance of caution.

Little did she know, she'd wind up paying a steep price for her momentary lapse in judgement.

Yes, as you may have heard by now, DeJesus caught an STD from baby daddy Luis Hernandez.

Understandably, Briana says she felt frustrated and humiliated upon learning the bad news.

But Briana allowed MTV to document this difficult chapter in her life in the hope that others might learn from her example.

Since Teen Mom 2 essentially started out as a show documenting the dangers of unprotected sex, we guess the series is staying true to its mission by following Bri on this painful journey.

In a preview for Tuesday night's episode, we see DeJesus and her friend Shirley making a nerve-wracking trip to Planned Parenthod so that Bri can get tested.

"Since we had unprotected sex, today I'm getting tested for STIs," she says in the clip.

"If I have something, I don't even know what I'm going to do. I'm so nervous."

"Next time you're gonna have sex with Luis think of this exact moment," Shirley tells her.

Maybe it's not the most supportive comment in that moment, but we suppose Bri's friend has a point.

To her credit, Briana doesn't shy away from sharing the more embarrassing details of her encounter either with her nurse or with Teen Mom 2 viewers.

"Have you ever had sex while intoxicated?" the nurse asks her.

Briana winces and answers in the affirmative, an acknowledgement that she was drunk when she hooked up with Luis.

DeJesus consents to both blood and urine tests, in order to ensure that she's screened for chlamydia, gonorrhea, syphilis and HIV/AIDS.

She also reveals how many sex partners she's had in the past 12 months and sheepishly admits to not always using condoms.

Obviously, there's no shame in getting tested -- in fact, it's something to be quite proud of.

But this clearly wasn't the proudest moment in DeJesus' life, and she deserves credit for allowing it to be filmed.

"My mental health wasn't there and I did something that I regret, but I ended up catching an STD and I didn't think anything of it," Briana told People magazine in a recent interview.

"I thought maybe letting MTV film this personal experience would be a learning experience for others, to teach others that it's okay to get tested and it's okay to talk about it," she continued.

"And that kind of bit me in the ass because something came up positive in my test results and they definitely filmed it all."

Despite the difficulty of living out these moments on camera, Briana says she has no regrets about allowing MTV to follow her to Planned Parenthood.

"I hate that I have to relive it over again because I'm finally over it, but hopefully it's more of a learning experience for everybody else," she added.

"I hope people can learn from my mistakes because I've made tons of mistakes."

At its core, of course, the Teen Mom franchise is all about dealing with the fallout from mistakes.

We applaud Briana for offering up her own story as a cautionary tale.
