Actually the women who post here are trying to find ways to be able to conceive, but...what you're doing sounds like the ideal to me. Be aware of your fertility signs and use condoms when you are potentially fertile. Synthetic hormones are bad for your body any way you look at it and I've seen so many women posting on this site who've had problems with IUD's. If you are allergic to latex why not try condoms made of something else, say polyurethane?
