AislynRae: You might consider the Fertility Awareness Method (NOT the Rhythm method which is based off the stupid idea that we all menstruate every 28 days. Pfft.) Taking Charge of Your Fertility is an amazing book and is available on amazon, both for getting pregnant and preventing pregnancy. Also, um... Pine needle tea is amazing for your body, but has been linked to miscarriage in cows and humans, likely due to the extremely high vitamin C content. NOT advisable for preventing pregnancy, but there is a book out there called Hygeiea - A Woman's Herbal by Jeannine Parvati that goes into permanent or temporary sterility.
Mahala: It sounds like a possible hormone imbalance. Maca is fabulous at regulating hormones, and it makes men super-fertile. It's a peruvian root and an adaptogen, so all-around goodness. Licorice also acts like estrogen, so you can take licorice daily almost like a hormone pill. It's very good for you, too. MANY healing properties. It can be used to put your body back into balance. Magic-wise, moon rituals and ocean rituals would be helpful. Go with your gut and guidance rather than following one laid out in a book, as a woman's cycle is so deeply personal to her, and although much information can be gained by one's sisters, honouring your own power might be helpful.
