The former SPICE GIRL - who is expecting her first child with singer boyfriend JADE JONES in the summer (07) - suffers with endometriosis, a condition which runs in her family and can affect fertility.
She says, "I was worried that maybe it wouldn't happen for me or that things may be quite slow.
"I couldn't believe it when we were lucky enough for things to happen quickly. I'm over the moon."
