Vicky Pattison said she broke down in tears after being forced to halt her fertility treatment.
The Geordie Shore star, 35, has decided to freeze her eggs as she plans for a family with fiancé Ercan Ramadan.
However, sharing a photo from her hospital bed, the reality star said things hadn't gone to plan.
"Unfortunately yesterday didn't go as planned and I have another cyst on one of my ovaries," Vicky revealed.
"As the injections I would have to administer as part of my fertility treatment are predominantly oestrogen- rather than stimulating the ovary follicles which is what we want to happen- it would end up instead predominantly feeding the cyst and treatment would be wasted."
The reality admitted she was "naturally a little bit disappointed and spent most of yesterday crying and just feeling super drained," adding "it was as if someone had let all the air out of a balloon".
Vicky did say her case was "pretty common" and that she was bracing herself for 'more ups and downs'.
She continued: "I need....to be thankful that I'm in a position to have options- which I truly am. And I want more women to know that it isn't easy for lots of us.. and you're not alone. No matter how it may feel.
"I've made my peace with this today- I'm going back to work, I'm going to focus on other things and I will try again next month."
Vicky's positive post was met with a flurry of support from her followers, who praised the TV star for being so candid.
One said: "Bless your heart. I went through this in my twenties. It’s so very difficult. You have a great attitude towards everything."
While another wrote: "You are a fighter, and you sharing this with everyone instead of closing the door on the world, you are brave."
Vicky told fans fans she and Ercan had taken the first proper steps to becoming a family in December.
Sharing a snap of the couple standing outside a clinic, she wrote on Instagram : “Last week @ercan_ram and I took our first proper steps to hopefully adding to our family in the future.
“I haven't posted about this as I haven't really known what to say and stupidly everytime I do start typing about it, I cry - and I really haven't needed more of a reason to be tearful recently with my bloody period still making me seem completely emotionally unstable.”
Vicky continued: “Anyway, I just wanted to say a big thank you to the amazing team at @londonwomensclinic who were so kind, understanding and just lovely to us as we were pretty nervous and emotional.”
