Csi: Miami star Emily Procter fell pregnant a month after she and her partner gave up on conceiving a child via in vitro fertilisation.
The actress, who became a first-time mum at the age of 42 in December (10), admits she'd resigned herself to the fact she would have to adopt if she wanted to start a family with boyfriend Paul Bryan - and then she discovered she was with child.
Procter tells the new issue of Parade magazine, "We did Iui (intrauterine insemination) and two rounds of Ivf, and nothing worked.
"We considered adoption, but the process takes so long. In the end, we gave up on the treatments, and the very next month, I got pregnant naturally."
And she admits baby Pippa has helped her get to grips with questions she has about her own biological parents.
Procter, who was adopted at birth, tells the publication, "I adore my parents, but I always wondered if I would feel a different kind of love... for someone who was biologically related.
"I couldn't wait to look at someone who shared my genes. I thought my baby was going to provide a decoder key to my past. But then I looked at Pippa and realised, 'No, she's actually the key to my future.'"
And that will include an adoption: "In a few years, once Pippa has settled in, I think we'll probably adopt a child who's over five, because older children often don't get considered for adoption."
