AFTER going through the menopause at age 20, Allison Noyce was told she could never have children naturally.

    So when she went to the doctor with stomach pains 15 years later, she was astonished to learn that she was pregnant — and the baby was due within days, the Daily Mail reported.

    The 36-year-old was afraid she had cancer when she felt pain and found a lump in her stomach, the report said.

    Instead, medics told her she was eight months pregnant, and just 12 days later she gave birth to daughter Sophie, who weighed 2.84 kg.

    Noyce said: “Sophie is truly a miracle. We simply couldn’t believe it when doctors said I was not only pregnant — but so close to delivery.”

    The fitness instructor became alarmed when she felt unusually tired after one 64-km bike ride.

    She said: “Around the same time I noticed pains in my tummy, and over the past few weeks, I had thought I could feel a lump. Terrified, I booked an appointment with my GP.” Her doctor believed the lump was “probably a large cyst” and quickly sent Noyce to a hospital for tests.

    She was sure pregnancy was not a possibility because at age 30, after marrying her husband Richard, she had gone back to the doctor’s to double check that she would never conceive naturally. Noyce went through menopause in her 20s.

    “In hindsight I’d had other signs, but put morning sickness down to a virus and tiredness down to being busy.”

    Most women experience the menopause — a natural change in the body’s sex hormones — between 45 and 55.

    In rare cases, some women experience menopause before they reach 40, often for no known cause. This premature ovarian failure affects about one in 100 women before 40, and five in 100 by 45.

    Over a decade the pair traveled the world and pursued hobbies such as long-distance bike riding and hill walking.

    But they were delighted to learn the doctors had been wrong, and couldn’t wait to tell their stunned friends and family the news.

    In July 2013, she woke with contractions and five-and-a-half hours later Sophie was born.

    Sophie is now 16 months old and the Noyces still can’t believe she’s here. (SD-Agencies)
