I know people can be harsh. I’ve certainly tried not to be. You 2 have been married less than a year, right? I’m not sure what kind of trouble NFP gave you, since you won’t elaborate, I can only guess, which may get me into trouble, but anyway. I’ll share my story and maybe it will help.
My husband and I are converts. We converted 2 years into our marriage. I used the pill and it made me very ill all the time. When NFP was presented to us as a licit way of spacing births, I was thrilled. When I learned what the pill did I was horrified that I could have aborted many babies in 2 years. Yikes. We went to CCLI classes and learned the method prior to Easter and realized we had been waiting to start our family for no really good reason. So, off we went. A little less than a year later, we concieved. We were not well off. DH was a grad student and I was a music teacher at a Catholic school. We were not rolling in the dough. Thankfully, dh and I could split childcare and we didn’t have to do daycare with our first. My cycles tend to be really long. 36-60 days. That means phase 2 can be exceedingly long. So we abstained when we had to. What helped is dh was on board with NFP for spacing but also NFP and the Church had softened our hearts to having more than 2.4 children. When we were contracepting the idea of having more than 2 children was never even an issue. Each time we have added to our family, it has never been a surprise–we knew when we were not following the rules and we were okay with that. We dealt with the long phase 2. Sometimes it WAS hard. No one should ever claim that NFP is an easy thing to do. Sometimes it is, and sometimes it’s not. But, usually, no kind of fasting is easy. It’s not supposed to be. We should be growing in faith during those times of fasting, whether it’s from food or sex, or tv or chocolate or whatever.
I also wanted to add, that there are other forms of NFP that might be better suited to you:
ccli.org which is the sympto-thermal method
boma-usa.com which is mucous only
creightonmodel.com which is a medical model of mucous only
nfp.marquette.edu/ this is various fertility signs along with the fertility monitor (they have a forum as well)
Some women find STM too complicated or not suited to their personality. There are other options out there.
You are newly married. I hope that you continue to pray and seek the truth about this, that you don’t stop growing in faith over this matter, because some priest said it was okay to use condoms. There is more to the teaching than this forum can provide. If you need further references or information, please don’t hesitate to ask–maybe privately.
