Mum fears she has to have a tumour removed, but is left in total shock

When Leanne Allen was suffering with kidney problems she hurried to the doctor's office, concerned about her condition. 

The mum-of-two had been tired and putting up with severe swelling of the legs, alongside her deteriorating kidneys. 

To be on the safe side, her doctor in South England sent the 37-year-old to undergo an MRI in a bid to find the source of the problem. 

But when the doctor revealed she had indeed found something on the scan, Leanne was immediately scared they had found a tumour. 

Mum to a 14-year-old daughter and 12-year-old son, she was hoping her fears wouldn't become reality.

Sent to the operating table within hours, Mum wasn't having a tumour removed as suspected. 

She was having a C-section, because Leanne was 31-weeks pregnant with her third baby. 

Doctors feared Leanne could have pre-eclampsia, opting for the caesarean as soon as possible. 

According to Inside Edition, the now mum-of-three had no idea she was expecting, with their latest addition, Baby Harley, being the ultimate surprise for Mum and her husband Kevin. 

Suffering a miscarriage a year previous, Leanne and Kevin, were left with such heartbreak they had agreed their hearts were full with the family they had. 

Nonetheless, their family-of-four has now become that of five, and they couldn't be more happy. 

Telling her daughter and son about the new arrival made for some funny reactions as like their mum and dad, they had no idea they were about to have another sister. 

Could you even begin to imagine the shock?

We're so glad to hear that both Mum and Baby are doing well, that's the most important thing.
