My answer: Fertility Awareness Method
I've used fertility awareness method (FAM) with my husband for 4 1/2 years and it's been effective thus far! You just have to get used to taking your temp every morning (or just during your fertile phase) and to checking your vaginal fluids. It's super easy! We just avoid sex when I'm fertile (or we use a condom) and we have sex when I'm not fertile. Takes the guess-work out of it!!
Get this book: Taking Charge of Your Fertility
And visit this website: Taking Charge of Your Fertility
The information in the book will blow your mind. I was sooo mad that I hadn't been taught any of the information found therein while I was in biology class or sex ed in high school. We should all know this stuff!!
And yes... GET OFF THE PILL!!
Also, I was horribly hormonal (depressed, pissy, bitchy etc) while on the pill for 6 weeks right before our wedding. So much so that I only lasted 6 weeks on the pill before figuring out FAM and dumping my pills in the trash.
