Kate Middleton pregnant: Sales of fertility monitors soar as women try and match The Duchess of Cambridge

Her wardrobe sparks sell-outs. Her shoes are the subject of intense debate (not by us - we don't have a clue what she's wearing).

But it seems there is another Kate-ism that women are desperate to copy:

Her pregnancy.

Yes, despite her hospitalisation for extreme morning sickness, the rumoured need for hypnotherapy and the international bump watch that follows her around, women are keen to catch up with Kate in the pregnancy stakes.

Clearblue (the pregnancy and fertility products company), has seen a 60% increase in sales of its fertility monitors since the Duchess of Cambridge announced her pregnancy in December.

The company claims that the rise in sales of home fertility monitors and test stick packs is the biggest increase in five years, and puts it all down to Windsor Womb Watch, as couples try and coincide with Kate and Wills, who are due to welcome their first child in July.

Clearblue UK Brand Manager Hugh Ayling said, "We've never seen an increase like this before. We were pretty stunned when the stats came in and we wondered why it was. Then we worked it back and saw the spike came after Kate made her announcement.

"It would seem that women are trying for a baby in the hope of experiencing their pregnancy alongside Kate. The nation is still obviously in the throes of Royal fever following the Royal wedding, Jubilee and now the announcement of a Royal Heir."

All a bit depressing, no?
