Holly Willoughby thinks she has made herself anaemic.
The TV presenter - who is currently expecting her second child - had to miss hosting 'Dancing On Ice' on Sunday night (27.02.11), and was absent from her slot alongside Phillip Schofield on 'This Morning' yesterday and today because she was feeling unwell.
After being checked over at a hospital, the 30-year-old star believes she has given herself the blood condition, which has been causing her to suffer debilitating migraines.
Speaking at the start of 'This Morning', Holly said: "Morning! I feel much better today thank you. To be honest I'm not sure what was wrong.
"I just felt really unwell on Saturday so I went to the hospital to have some checks done and I'd managed to make myself quite anaemic and I think the headaches were because of that."
Holly - who already has a 22-month-old son, Harry, with husband Dan Baldwin - has been taking medication given to her by her doctor, and is hoping she will be back on the show tomorrow (02.03.11).
She added: "You obviously have to be guided by your doctor - I mean they gave me things to take which have eased the pain a bit but also made me quite sleepy, so it was just one of those things really and another thing that comes with being pregnant.
"I think I'll definitely be in tomorrow."
