Kym Marsh in hospital

Kym Marsh is being kept in hospital while doctors monitor her pregnancy.

The 'Coronation Street' actress - whose son Archie died in February 2009 after he was born 18 weeks early - has been in hospital for almost a week after medics reportedly prescribed a steroid treatment that allows babies' lungs to develop fully while in the womb, but is hoping to be allowed home soon.

Kym - who is engaged to 'Hollyoaks' star Jamie Lomas - is currently 27 weeks pregnant with a daughter and show bosses have given her early maternity leave in order to focus on her health.

The 34-year-old star - who has been diagnosed with an incompetent cervix, which can cause premature birth or late miscarriage - also has two children, David, 15, and 13-year-old Emily from a previous relationship but recently revealed this will be her last pregnancy.

She said: "I can definitely say my childbearing days are over. I couldn't go through this again, it's too heartbreaking. We don't know the exact problems we had with Archie. I hate that term late miscarriage as I gave birth to Archie when he was a fully formed human being.

"This pregnancy has been really difficult, a nightmare in fact. We've been on eggshells. But it's lovely when we see her on the scan and when I feel her wriggling."
