The old celts often prescribed a strict diet, now referred to as the Oimelc Diet, when it came to fertility and conception.

Oimelc is the celtic term for both ewes milk and the early part of February when the new lambs are birthed. 

When you decide that its time to conceive simply incorporate pasturized ewes milk, yogurt, hazelnuts and honey into your daily diet. 

Though now days, ewe's milk is considered to be a "new age health fad," in the past it was an essential dietary staple and one that was often used over cows milk as it is easier to digest.
