Menstrual Cycle and Pregnancy is a precious piece of write up that all those who study it and follow it will have their lives turn around for better. Menstrual Cycle and Pregnancy give a detailed understanding of the menstrual cycle, right from its beginning as an adolescent, right up to pre-menopausal and menopausal women. It gives authentic advice on natural family planning using what is called the 'Billings Method' to avoid pregnancy as well conception for the childless women. The only way to get the preciousness of this book is to study it in detail and use it as a consultant all the time. I called it "Women's Companion" because they need it all the time to clarify every doubt and keep life going in the way they want, when it comes to family issues. I will plead that no one should make any assumption and in case of any doubt, called the author for more detailed explanation for a better understanding. Any assumption without understanding will get you more confused and the method will not work as you expect.
