During aBravoAll Stars OG Housewives panel atBravoConin New York City, the formerReal Housewives of Atlantastar revealed on Friday that she and husbandKroy Biermannare thinking of adding to their family that already includes six children.

“We’re on the fence. I’m 41. I know the clock, it’s ticking along. You’ll see in about six months or so if I do decide,” Zolciak-Biermann said. “I’m going to have to hurry up. If we’regoing to do it, we’re going to do it.”

“Kroy and I talk about it all the time,” she continued. “The kids are all in school, so it’s a nice break, and Kroy never really got a break when the kids were all babies, except during the NFL lockout.”

The reality star and former Atlanta Falcons player Biermann, 34, share twinsKane Ren and Kaia Rose, 6 this month, plus sonsKash Kade, 7, andKroy “KJ” Jagger, 8, and daughtersAriana, 18, andBrielle, 22.

Speaking with PEOPLE exclusively following the panel on Friday, Zolciak-Biermann said they would try a vasectomy reversal first if they diddecide they wanted another child. But as Biermann admitted of the potential procedure, “Sometimes I’m into it, and sometimes I’m not.”

They’d also consider adoption, Zolciak-Biermann told PEOPLE — but not surrogacy.

“I’m such a control freak that I’d have to know what [the surrogate] was up to every day,” she admitted. ” ‘What are you eating? How are you sleeping?’ … I have to give it to people who can do it, likeKandi [Burruss]. I really could never do it.”

During the Friday panel at BravoCon, Zolciak-Biermann gave an update on her kids, saying she “cried for days and days” over thinking about Ariana going off to college soon.

“Brielle, she’s back home, thank God! We started a cosmetics line together —me, her and Ariana — andshe’s very involved with that,” the proud mom continued. “KJ, he’s an athlete. … Kash [is] a Leo. He has a big ego. The twins will be 6 next week.”

“Thetwin connection isbizarre. Something I will never understand,” Zolciak-Biermann said. “It’s a connection that Kroy and I, daily, are amazed at. They’re best friends. The twins are great.”

She also talked to PEOPLE about thebullying her daughter Arianahas faced over her weight, saying she “always [tries] to encourage my kids to be who they are.”

“KJ is big — he’s a whole head taller than anyone in his class. Than anyone in thegrade, pretty much,” Zolciak-Biermann said. “So he’s dealt with the bullying when they have recess and they play football.”

“They don’t want KJ to be the quarterback because he’s too big. And it hurts his feelings because he has such a tender heart,” she explained.

“So when it comes to someone like KJ,with the bullying, I’m at the schooland I’m dealing with the teacher and the principal,” Zolciak-Biermann shared. “They don’t put up with any of that in his school, so that was nipped in the bud.”
