Does anyone have any information comparing fertility monitors to prevent conception?
I know that there are several types that are available in Europe that claim to be very reliable but have only been approved by the FDA for conceptive (not contraceptive) purposes in the US.
I am curious which is more reliable monitoring
Basal Body Temperature, LH & E3G, electrolyte levels?
I am currently breastfeeding and my periods have not returned. My husband and I are open to learning and practicing Fertility Awareness or Natural Family Planning methods, but would like to have monitors as a double check on fertile and infertile points of the cycle.
