Fertility spells are used for women who are trying to get pregnant, and are looking for a little magickal boost to help out Mother Nature.
Just remember that fertility spells can only do so much and that proper medical treatment and care is a big part of having a healthy conception.
Fertile Harvest Spell
Use the power of a the grain harvest to increase your fertility. If you can't find wheat heads, you can get natural "wheat berries" or unprocessed whole wheat grains at a bulk food store.
Anoint the candle with a little oil and light it. Light the incense as well. Place the pine cones and pieces of wheat into your bowl.
While you focus your intentions on getting pregnant, write the name of your future child on the paper. It's just a symbolic name, so don't worry if it's not the exact name you really want. It should be something you can believe in and concentrate on though.
Place the paper in the bowl, and light the contents on fire. Watch it burn, and continue to think about your intentions. When it's done and cooled, bury the ash and any remaining bits of pine cone in the yard.
Buried Egg Spell
This fertility spell is already on the Earth spells page, but it certainly fits in here too. All you need is an egg, a whole vanilla bean and a pencil or marker to write on the egg. The waxing moon phase is the best time for this spell if you can.
First, write these symbols on the shell of your egg. The letters are in Theban, and the word is "ripe". Once written on, you have to bury the egg along with the vanilla bean. It has to be at least a foot deep or more so that animals don't try to dig it up. If you don't have access to outside space for this, use a large planter or bowl of soil inside the house instead.
Once buried you have to water it each night so that it can "grow". If you are using a pot indoors make sure it drains or this will get soggy pretty quick. This should increase your chances of conceiving as long as you keep watering it each night with focused thoughts on having a child.
