First, explore all methods. Not all methods use temps. That doesnāt work for some people
Second, start charting now in case you have health issues that need to be cleared up first and you discover them from charting.
3rd, there is a vast difference in the philosophies between creighton and sympto-thermal. Apparently, ST method lets you shave off days, or lets you determine whether you are being āconservativeā in your avoiding pregnancy or not, and so there are āiffyā days.
Creighton is absolute black and white. For example, If you engage in intercourse before the night of peak plus 4, then you are no longer using the method to avoid pregnancy, but to achieve.Thereās no āiffyā in there. There is a possibility of pregnancy in there. (Iām not including pre-peak here, this was just an example).
I bring this up because I see people that say they use online charting and read books and things, but donāt mention they went to a teacher (they could, I donāt know). My concern here is this: people get pregnant when they SAY they are using NFP to avoid, but in actuality, they werenāt educated in everything, or they hadnāt been charting very closely, or they hadnāt been checking up with a teacher, and then this discredits NFP even further.
Iāve been doing creighton NFP for 5 years for my health (Iām single). Iāve used it successfully to determine 3 different health issues with my doc. I know that after awhile you get to know your body closely, and can confidently determine a lot of things without lab conditions, however, Creighton is very clear that if you want to trully rely on NFP for success (because there are definate serious conditions that people canāt get pregnant), then one must chart meticulously, go to their teacher, etc.
