Hello, I am Rachel. For right now I am just trying to get the temerature part. I won't worry about the CM or things like that Until a few months before I want to become pregnant. Is there problems doing this while on horomonal birth control? I don't want to do NFP because I am not determined enough...it would be more like chance to me. I do want to get to knw my body and it's cycles in order to get pregnant, but that isn't going to be until 2009. So far with temping, my temps have been all over the chart, or a lot higher than most that I have seen. I have only gotten 1 reading lower than 98.0. I may be jumping the gun a little to soon, but there is a link to my chart.

Yes, being on hormonal birth control makes it impossible to chart. The synthetic hormones will create a phony cycle for you and your signs of fertility will be untrackable. If the hormone is strong enough to suppress ovulation, then there will be no ovulation to detect. If it is a progesterone only contraceptive, you won't detect a thermal shift with your temperatures because progesterone is what makes them rise after ovulation. Synthetic hormones also work by thickening or drying up your cervical mucus, so you won't be able to accurately observe that either. When breakthrough ovulation occurs while on synthetic hormones, it's a secret - because usually the other signs we can track are also affected by the contraceptive, so there's no way to know for sure.

You can practise temping just to get the hang of it, but it won't offer any information about your fertility with synthetic hormones on board.

NFP is highly effective with proper training, hardly like chance. Clinical trials in China found one NFP method more effective than the IUD. Similar trials found the same results in India. The old Rhythm or Calender Method was a lot like chance, but that is nothing like modern methods of NFP. Not learning a method properly is also like chance, because it is important to learn the rules for avoiding pregnancy very thoroughly. If a woman is determined enough to brush her teeth every day, she's determined enough to chart every day and use NFP. I've actually never seen a true NFP method-related failure, only user-related failures from not having proper instruction or choosing not to follow the rules for avoiding pregnancy - which is the same as choosing not to take a pill every day and getting pregnant. LOL Will include a few links about the clinical trials about the effectiveness of a few different forms of NFP below:

Clinical trials of the Billings Ovulation Method and associated research: 99.6% effective
