Season 11 "Bachelorette" contestant Kaitlyn Bristowe sat down with "Good Morning America" on Wednesday to discuss a big decision she and her fiance Shawn Booth had recently made: namely, to freeze her eggs.

"I think a lot of women feel pressure to have kids, especially when you get engaged," Bristowe told GMA. "And for me I'm like, I don't want that pressure on myself."

The 31-year-old opted to use Ova Egg Freezing, an egg freezing specialty center in Chicago...

...along with fellow former "Bachelor" and "Bachelorette" stars Carly Waddell and Andi Dorfman.

Other celebrities, like Olivia Munn and Whitney Cummings, have also shared that they've frozen their eggs — which has given way to a larger trend: millennial women in general deciding to "stop the biological clock" by undergoing the same process. According to the Society for Assisted Reproductive Technology, the number of women who decided to freeze their eggs between 2009 to 2013 increased by almost 10 times.

The increase in young women making this decision has also given rise to a number of new startups aiming to make the process affordable.

Egg freezing can cost tens of thousands at some clinics; companies like Ova tout their affordability: Prelude, for example, offers a subscription-style mode of pricing for $199 a month; Extend Fertility offers the service for under $5,000.

It's still a high price to pay, depending on how long one needs one's eggs frozen for, but maybe not too high for the ability to focus on one's career, to find a partner with whom to have kids, or even just for peace of mind.

"This is kind of a backup plan for us, for us to feel comfortable," Bristowe said. "It's kind of like insurance."
