Teen Mom 3's blondest bombshell, Mackenzie Douthit, has a pretty idyllic life. This southern belle has a handsome cowboy on her arm, a buncha pom-poms on her other arm, and two adorable children who love her more than anything in the world. Oh, and she isn't even 21 yet!

It's no secret that Mackenzie is pretty young to be a mother of two, but this girl had a very specific reason for getting pregnant for the second time at the tender age of 19. She has Type 1 diabetes, and doctors have told her that she won't be able to safely bear children past the age of 21.

While Mackenzie hasn't announced plans to have any more kids, her window of time to expand the Douthit-McKee family is definitely shrinking and this gal recently took to Twitter with a vague musing on birth control.

"What I've learned today...breast feeding is NOT birth control lol," she tweeted on April 21.

You guessed it guys, the time has come to speculate. We know Mackenzie breastfeeds her baby daughter Jaxie (and plans on doing so until she's one), and it appears as though she hasn't been using birth control as a result! And while women are less likely to get pregnant while breastfeeding, it's definitely not foolproof.

Do you think Mackenzie learned her lesson the hard way and is baking another bun in her oven? Hit the comments and let us know!
