Catelynn Lowell is not letting the critics have the final say. 

Days after the Teen Mom star shared that she and husband Tyler Baltierra had been blocked from communicating with their biological daughter Carly by the 15-year-old's adopted parents, Brandon Davis and Teresa Davis, Catelynn is responding to claims that Tyler forced her to give their child up for adoption in 2009.

"I'm seeing the comment a lot that people are saying that Tyler gave me an ultimatum," Catelynn began in a Sept. 19 Instagram video, "either my baby or him. First off, that comment is absolutely disgusting on so many levels."

The way the 16 and Pregnant alum sees it, when people say something like that, "it strips me of all of the strength and sorrow that it took me as a birth mom to place my child."

Catelynn doubled down on how false the accusations are. "If you think that I would just give my baby away for a man, that is absolutely untrue," she noted, "and to think that I would still be with said man after all of these years, if he did give me an ultimatum with either my baby or him, that's absolutely disgusting."

According to the 32-year-old, both she and Tyler, also 32, did want to keep Carly, but they knew adoption was the better choice for them, which echoes a sentiment Tyler had previously expressed.

"I know that there was a scene that was filmed that Tyler said that he thought that if we would have parented Carly, that we would not be together," she continued. "He's not implying that if I didn't place Carly, he would have broke up with me."

As the Catelynn explains, Tyler's comment had more to do with the fact that teen parents "typically do not stay together," noting that a majority parents on their show who kept their children are now broken up, while she and Tyler have been married since 2015 and share daughters Novalee, 9, Vaeda, 5, and Rya, 2.

"Teen parents go through stress and all of the things to raise a baby," she said. "So I agree with him. If we would have kept Carly, we probably wouldn't still be together."

And ultimately, she and Tyler are thankful for the choice they made because it gave them the life they have now.

"I guess at the end of the day, believe what you want," Catelynn said in conclusion, "but just know when you think things like that, it strips me of all of my strength as a birth mom and the strength of Tyler also being a birth dad. It's disgusting that any of you guys would think like that."

Over the past few days, the MTV star has not held back about sharing her frustration regarding the situation with Carly, especially because feels it's unfair to Carly and her siblings.

She also believes she was initially blocked because Carly's parents felt scared or threatened when the teen was asking "questions about why we don't get together anymore."

"When you're a bio mom you have no say... no control," Catelynn wrote on Instagram Sept. 9. "All I can do is show Carly in the future how much I tried and continue to do so... she can make the decision herself to understand who shut who out."
