"I wasn't trying to get pregnant," the reality star says of the first time she conceived

The experience of trying to get pregnant is well known to vary from couple to couple. But Kelly Killoren Bensimon isn’t one of those women who planned out her first pregnancy and kept trying to conceive until it happened.

“I wasn’t trying to get pregnant. I was modeling and traveling a lot, and was sometimes really really thin,” the Real Housewives of New York City alum shares onPEOPLE’s Mom Talk.

“And periods [were] really irregular,” Killoren Bensimon, now 48, adds. “I never thought I was going to get pregnant.”

Killoren Bensimon adds that, when she was 19, a psychic told her she was never going to have children (she is now mom to teen daughters Thaddeus Ann and Sea Louise). So when her doctor told her she was pregnant years later, she didn’t believe it at first.

“When I got pregnant, I was like, ‘I’m not feeling like myself, I’m feeling like someone else,’ ” she says. “And my doctor was like, ‘You’re pregnant,’ and I was like, ‘It’s impossible. The psychic told me.’ ”

Jacqueline Piñol, 37 — who also voices Pepito Gonzalez in Bordertown —is another woman who wasn’t sure what her parenting future was going to look like. She and husband Jonny Blu own four dogs, and were operating on the adage “If it happens, it happens” — and happen it did, with the arrival of 4-month-old son Atlas.

“Sure enough, the first time [we weren’t] careful, boom,” the former CSI: NY actress chimes in.
