I LOVE charting!! Being Catholic and all, it's the BEST option for the hubby and I. I know their are books and websites that are great, but we actually took a class in our hometown. We actually were recommended the class from our priest before we got married, sooo maybe you can call a Catholic church or a Catholic charity or possibly a Catholic hospital, if any are near and see if they can hook you up with a class. The class was a lot of fun! We were with 3 other young couples like us, some were trying charting to postpone pregnancy and some were trying charting to help get pregnant. They were awesome people! The teachers were very knowledgeable and were available to call anytime if we had, or currently have, any questions. It was 5 classes for $40. We even got this HUGE booklet to take home for references if/when we needed them. The big booklet is SOO nice!
