Last month, Lowry confirmed to PEOPLE that she'd welcomed her fifth baby, son Rio, with her boyfriend Elijah Scott last year. This is the first baby for the couple, however, the reality TV alum also shares sons Creed, 3, and Lux, 6, with ex Chris Lopez, 9-year-old Lincoln with ex Javi Marroquin and 13-year-old son Isaac with ex Jo Rivera.

"I wanted to be able to tell my own story on my own terms and kind of share what information I wanted to share instead of being within a contractual obligation or storyline," Lowry, exclusively told PEOPLE about why she kept her son a secret.

But Lowry, admittedly, wasn't necessarily "ready" to share her private family news. "I feel like it was ripped out from under me time and time again," she explained. "I kind of feel like my hands are tied. People are announcing it for me and so, at this point, I might as well just talk about it."

"At this point, I can at least try to do it my way," she continued.

During part two of her tell-all discussion about her family life on her podcast Barely Famous, the pregnant podcaster shared that she's "excited for my kids" as they prepare to welcome the twins.

"Now I feel like our family is complete — I won't have anything missing. I won't feel like, 'What if we had another one?' I'm excited to explore this motherhood journey in terms of privacy and putting out what I want to put out. I'm excited for that," she explained.

"I'm a little nervous about having four babies in one month. I don't know what birthday parties are going to look like, but I'm excited to see how this goes. Isaac is going to be driving before I know it, so it's just a bunch of milestones all at one time — lots of new beginnings and also closed chapters, I feel."
