Whitney Port is feeling "hopeful" about having another baby

Speaking on her With Whit podcast, Whitney said: "The surrogacy journey is on a positive trajectory.

"We just signed our contract and are now awaiting next steps for a transfer, but it's hard to explain unless you're in it.

"It's hopeful and it's exciting, but it's also tiring and exhausting, like, you have all the hope in the world and you want to spread all this positive energy, but you've also had such failures that it's hard for you to imagine anything going right."

The couple turned to surrogacy after suffering multiple losses after having Sonny, and tragically some of their surrogates have also miscarried following embryo implantation and Whitney admitted she has conflicting emotions about their next attempt.

She said: "Some days I feel fragile, other days I feel scared.

"Most days I feel, like, 'Let's go, let's do this,' and most of the time, I feel all of it in the same hour."

Whitney noted that "the legal portion" of the process is complete after signing a contract with their new surrogate but she feels they only have a few attempts left.

She said: "Now it becomes a little more of the science-y, nerve-wracking part.

"We'll schedule a transfer in the next one to two months and just cross our fingers. We have three embryos left, and they're all boys.

"I've kind of told myself right now, 'If these three don't work, we're probably not going to continue to try.' "

While the reality star wants to be positive, the "logical part" of herself is prepared for all potential outcomes.

She said: "I also don't want to be getting too ahead of myself or even visualising or thinking about the fact it's not going to work, like, that doesn't help the situation at all. I'm a firm believer in manifesting and visualising something and throwing positive energy out on it....

"[But] you have to have a plan and an idea in our head of when you will be ready for this journey to be over.'

"[I think there will be] some sort of actual tangible thing that will happen that will put an end on this 'cause I think, so far, we've just kind been going, going, going and just seeing how far we can take it [and] how much we can push these emotions.

"I just don't know that I could go through another egg retrieval situation. My eggs, year after year, after just getting fried and fried and fried to go through that process, get 21 eggs and then be able to get one maybe-healthy embryo. Part of me wants that chapter to be put [to the side] when we go through all the different scenarios."
