I hope I'm wrong here but Nikki clearly isn't maternal and probably never wanted kids but saw there was an opportunity to create content and gain more followers on the back of an ok but no longer booming Instagram page by going through the IVF process- a struggle means relatable, relatable means followers and followers mean ££££. She's literally gone through the process, I feel, for the gram, and now that her little career idea has failed and her 2 cashcows haven't given her the career she wanted she's stuck with 2 burdens she can't get rid of, stuck in a life she chose for all the wrong reasons and now there no way out! Lol.
