Yeah my temps did slowly rise which was worrying me at a point, but on so much medication this month and daily paracetamol for wisdom tooth removal which has been so wondered if that caused a slow rise.......my boobs only got sore once my temps really had risen so its like it took a while for the progesterone to rise in my blood or something, it may be that I OV'd CD 18 then......either way I BD'd at near enough the right time so lets hope this is my month!! Thanks for your input girls! ChattyB- crosshairs are meant to show after a miniumum of 3days high temps. xx
