I just looked her up: she had two miscarriages last year. From last month: 

Vanessa Marcil Giovinazzo who was expecting her second child, but her first with husband, Carmine Giovinazzo (CSI: NY) lost their baby via miscarriage.
Vanessa, who had told On-Air On-Soaps how excited she was to be a mom back in July, announced her pregnancy to all in June on Twitter.
Carmine took to Vanessa’s Twitter page to reveal the news stating, "V has had a miscarriage. our second one this year. thanx for the love and prayers. CDG."
