I went for a for a smear test today today and the nurse pretty much sneered about my natural famiy planning (persona machine temping and CM charting) she suggested a diaphragm.
We don't on the whole have lots of sex and this is why NFP is at the moment good for us
DH is quite keen as he belives the Persona is a hassle and I don't do it properly (cheek). I have been trained regularly read literature and am very strict and don't take any chances
But I would like to know what others have expperienced with them.
