That’s awesome! I love fertility awareness. My husband and I have been using Creighton for 5 years now with one planned pregnancy. I have a history of Endomeitriosis, low progesterone, and irregular cycles. Because of charting I can navigate my body’s biological markers and know when I am fertile or infertile. We really love the method we use because even with continuous mucus we are able to navigate poor quality mucus vs good quality mucus based on my body’s production and still have the majority of the month available for intercourse when we are avoiding pregnancy. Also because of charting we knew I had medical things that needed addressed. Sadly things that take an average of 7 years to get diagnosed. Creighton also can be used with limited mucus production (cervical secretions) in fact, when we see low production of cervical Mucus that can be a cause of infertility, hormonal imbalances, or a vitamin B6 vitamin deficiency. re:Infertility due to low cervical Mucus production, The female body needs basic things for non-medical assisted conception to occur. Good Sperm Good Eggs Good Mucus The absence of one of these and pregnancy will likely not occur.
