This is a new guideline from the FSRH on ‘Fertility Awareness Methods’ (FAM), otherwise known as ‘Natural Family Planning’. I have had a couple of patients interested in this, so it is worth knowing about. Apparently 2% of women in the UK use FAM for contraception.
There is also a bit on using the lactational amenorrhoea method, which I have added at the end.
If used correctly (which is the difficult bit of the whole method), there is less than 1 pregnancy per 100 women per year, which is pretty good.
