I have a question on Natural Family Planning and birth control. I have taken the NFP class with my future wife and we both agree and understand the NFP method. My fiancé has been of birth control for more than 3 years now and her cramps and pains continue to get worse. She is going to get back on the pill for medicinal reasons and in good faith and a clear conscience between both of us we have decided for medicinal reasons it would be best. We know the temptation is there to abuse the system when married, but our question is to be in proper accordance with the catholic faith do we need to obstain from sex during times when she is fertile if she is on the pill for medicinal purposes? We will still continue to plot with the NFP chart, but in good conscience are we only allowed to have sex during her non fertile times? I would like to know the proper action as a Catholic and really want to do the right thing and not abuse this. She really needs the pill for her medical reasons and we understand it will limit us and we would like to know Catholic stance on this particular situation we are in… Please help….
