my understanding is that there are two different methods, NFP, which is used by Catholics, and allows only for abstinence/non-intercourse activity during the "fertile" period, and FAM (fertility awareness method), which is like NFP in that you track your fertility signals, but during the "fertile" times, you can either abstain, OR use a barrier/chemical method.
so, they are similar, but FAM allows you to use "artificial" barrier/chemical methods during the fertile days in order to not conceive, whereas true NFP only allows for abstinence.
Is this right? Do we have any NFP teachers here? Please correct me if i have it wrong.
Anywho...although dh is Catholic, he doesn't agree with the church's take on birth control...in his belief system, he believes it to be a much greater sin to have children you can not provide for than to use birth control (non-abortificent methods ONLY!), so we use more of a FAM than true NFP, but since having my daughter, condoms and spermicide make sex too excruciatingly painful, so we are actually doing NFP right now, since my poor li'l battered hoochie can't take latex or chemicals right now, LOL!
