A mum is pregnant with her daughter's twin two years after giving birth to her sister, after years of fertility issues.
Research investigator Jennie Hill and husband John have spent over £46,000 on IVF to have their dream family.
The couple had two eggs fertilized at the same time in 2016.
They froze the second embryo as they didn't want to 'miss out' on the baby to toddler years with their first born.
Jennie said: "It is crazy to think I am carrying a baby that was fertilized at the exact same time as Harper in 2016.
"We did three rounds of IVF and managed to fertilize 47 eggs but only 13 embryos made it, during the five-day process there were a number of abnormalities and poor-quality eggs meaning only two survived.
"It was a miracle, John and I were over the moon, both eggs were inseminated at the same time, so they are 'medical twins.'

"I am a twin so I was thinking about inserting both embryos as I would love to have children with a bond like me and my brother.
"The doctor then informed us about all the risks of IVF twins, and if you miscarry one embryo, the other is unlikely to survive too; this was something we weren't prepared to go through with.
"I dreamed about being a mum since the moment I held a baby doll when I was a child, my heart broke every time I miscarried at 6-12 weeks."
Jennie and John, from Georgia, USA, are excited to complete their family, after so much heartbreak during their fertility struggle.

The 42-year-old said: "My mum Sarah, 63, who was 60 at the time, offered to be a surrogate for us but when I discovered I could carry the baby with IVF there was no need for surrogacy.
"We considered adopting but this was going to cost £38,000 so we decided to take our chances and go for IVF.
"I picked up a part time driving instructor job and John who works in sales and purchasing used some money out of his pension so we could cover the costs.
"I had always wanted children but after having Harper at almost 40, I realised soon after that having more than two babies at this later age might put me in a nursing home."
Jennie, was diagnosed with a balanced translocation after her fifth miscarriage.
It meant she was able to get pregnant but as the embryo grew, the chromosomes would break causing her to lose her baby.
She added: "With IVF, once they have inseminated the eggs, they tested the genetics of the embryos to see which ones are affected by a translocation and I had two left with a fighting chance of survival."

"I am a hopeful person and every time, I got pregnant I thought maybe this time is the one, so it was hard for me to enjoy pregnancy even with IVF.
"I am always thinking 'what if' and even four months in, John has to reassure me that everything is going to be alright.
"Harper is due to meet her sibling in September, we can't wait to have another rainbow baby to complete our little family.
"It is the most amazing thing being a mum, we are considering being foster parents in the future."
