A mum became pregnant twice in one week — after being told she had only a five per cent chance of conceiving after her first child.
Alina Luca went on to have daughters Ellie and Millie, who are not, medically speaking, twins.
She had given up trying for more kids before falling pregnant TWICE in one week just one month later.
Alina, of Beckton, Newham, East London, said: "I got pregnant while I was already pregnant. I didn't think it was possible.
"I asked the doctor 'are you serious? How can this be possible to get pregnant when you are pregnant already?'
"They said that it was very rare but it happens. We found out they were conceived one week apart because one of them was smaller on the scan.
"It's a miracle that this happened to me.

"We prayed for one baby and said 'if it doesn't happen we can't do anything about it', and then this happened after one month [of stopping to try] I found out I was pregnant.
"It was a big shock for us.
"After I processed it and did some research I was really in shock and was like 'wow, it really did happen and it really did happen to me'. It's really amazing."
Alina spent two years trying for a second child with partner Rick Carmea, but doctors warned her it was unlikely due to an underactive thyroid.
But a month later, the 30-year-old found out she was pregnant and during her 12-week scan discovered she was actually expecting two babies - that had been conceived a week apart.
The incredibly rare phenomenon is known as superfetation and is when a second, new pregnancy occurs during an initial pregnancy and can occur days or weeks after the first one.

The mum-of-three, who was already mum to a nine-year-old girl, found out she was expecting again last August.
Alina said: "I always wanted a big family. I couldn't get pregnant for two years and I gave up.
"They told me I had a five to ten percent chance of getting pregnant because I have Hypothyroidism.
"Last year I said I'd give up because I was upset and I was thinking there was no point trying again and if it will happen, it will happen.
"And after one month I found out I was pregnant. It was funny. I cried tears of joy because I was so happy.
"I called my sister and asked her to look at the pregnancy test to see if it was positive because I thought I was dreaming."
Alina gave birth to her two daughters on March 15th.
The pair were delivered at 35 weeks with Millie weighing 4lbs 5oz - who was conceived first - and Ellie following one minute later at 4lbs 4oz.
The full-time-mum has since set up an Instagram page in a bid to raise awareness of superfetation pregnancies.
Alina said: "The pregnancy was very hard and painful. I thought my back would break because my belly was so big.
"I'm small. My skin was so stretched and I had so many marks and was thinking my belly would explode soon.
"I was over the moon to hold them for the first time, it was amazing to be honest.
"You can see everything like double - not just because of having two babies, but everything - your emotions and you're more sensitive.
"When I tell people [her story] they look at me and they think that I'm crazy and wonder how it was possible.
"If someone told me before [her experience], I think I'd be the same."
