im 7 wks postnantal and still cant decide on a birth control method and so both my midwife and doctor have said that im pretty much covered by breastfeeding anyway so not to worry too much unless i decide to wean baby off and which case i need to sort out an alternaltive method.is this true? The doctor did say that with any method though it isnt 100% but didnt say what the percentage was for this method.Has anyone used this as a birth control method ?
