In recent times financial and career pressures have meant that more and more women are leaving motherhood until their thirties.

But doctors have warned today that those who haven't had a baby by the age of 35 may be leaving it too late.

Royal College of Obstetricians and Gynaecologists has found evidence to suggest that it is increasingly difficult for women over the age of 35 to become pregnant and those who do face higher risks to both mother and child.

The college suggest that the ideal age to have children is between 20 and 35 and there are concerns about the number of women delaying pregnancy until their mid- to late-30s.

As well as a greater chance of miscarriage, older mothers also run the risk developing preeclampsia and diabetes.

Mandish Dhanjal, a consultant obstetrician told the Daily Mail: "If you look at older mothers over the age of 35 – in the mid 1980s about 8 per cent of those women who got pregnant were over 40 whereas now that figure has more than doubled to 19 per cent."

Deputy general secretary of the Royal College of Midwives, Louise Silverton added: "Pregnancy complications can be more common in older women.

"They have higher rates of induction of labour and caesarean births, which present greater risks to both mother and baby.

"Despite this, we support a woman's decision to choose when to embark upon a pregnancy.

But with today's financial worries, many who might prefer to have children at a younger age are finding it increasingly difficult to achieve the financial stability to start a family.

Silverton went on: "Many women feel that they must delay pregnancy until their circumstances in employment allow."
