I started using the Creighton Model because my husband and I had been struggling with infertility for 2.5 years. I was always familiar with my cycles and thought I knew them very well but I ended up learning so much through the Creighton Model. After looking at my chart, Kristin discovered my chart indicated that I had low progesterone. Kristin immediately referred me to the NaPro Technology doctor and I was prescribed progesterone. Kristin also suggested I take vitamin B6 to help increase my fertile cervical mucus. After 2 months of taking progesterone and 1 month of taking vitamin B6 I became pregnant! Kristin is very knowledgeable about the Creighton Model and was extremely helpful in helping us learn the charting process which ultimately led to my pregnancy after just 3 months of charting. I will definitely be using the Creighton Model to chart my cycles again!
