The actress-turned-reality TV star fell pregnant with baby son Finn just one month after giving birth to her third child, but eight weeks into her term, Spelling realised something was horribly wrong when she began losing large amounts of blood.
She tells Us Weekly magazine, ""I was getting a massage at home and I felt wetness. I looked down and saw blood. My heart dropped. I started screaming for (my husband) Dean (McDermott) and told him, 'I just had a miscarriage.' But the next day I went to the hospital and the doctor said everything was fine.""
However, the bleeding episodes continued and she was soon found to have a condition called placenta previa, where the placenta covers the cervix.
She continues, ""My doctor kept telling me that at any point I could have a big bleed where they'd be forced to take me to surgery and deliver the baby. If that happened before 24 weeks, they said the baby wouldn't survive but they would do it to save my life. I was like, 'No! You have to save the baby!' He told me, 'You don't understand: If you lose enough blood, you could die...'
""It was so surreal. I just remember thinking, I can't leave three children behind... I kept thinking... 'Am I supposed to make videos for them? Should I write something down for them to have?'""
The former Beverly Hills, 90210 star then spent the next four months on bed rest to increase her chances of delivering a healthy baby, and on 30 August (12) she welcomed the little boy: ""When he came out, I couldn't wait to have him in my arms.""
However, Spelling's problems were far from over - three weeks later she was rushed into surgery when her Caesarean section scar burst, causing massive blood loss and requiring immediate medical attention.
The brave mum is now on the mend and she showed off her newborn tot in a special family photo spread for the publication.
