My husband and I have been using the Symptothermal method taught to us by Serena B.C. for almost three years now. We’ve found it helpful and effective for so many things. I have very irregular periods, with the Symptothermal method I finally know when my periods are going to be ahead of time so I’m prepared. For two years we used this method as birth control before deciding to have our daughter. Since we knew when I ovulated thanks to the charts provided by Serena we knew exactly when she was conceived which helped us determine an accurate due date for her. This made it easy to fill out paper work for the doctor when I was pregnant. She was born only two days before the due date we determined using her conception date. The charts provided by Serena B.C were easy to use and follow. For myself I find it incredibly empowering to know what my body is telling me, to be able to take charge of my fertility and periods without relying on something artificial or hormonal. My husband and I both like that it is a natural, effective way to plan our family without any possible unwanted side effects. We both have and would recommend this method to other couples.
