I've been ttc baby number 2 for the last few months. After watching my cycle observing cm and using opk's I realised that my luteal phase is only 9 days long. My gp wants to conduct blood tests 7 dpo. This month I've been charting and using opk's. On cd16 and 17 I had the classic ewcm but on both those days my opk's lines didn't match the test line in colour (quite weak). My temp has not risen and my cm is very wet but not ewcm ( sorry if tmi!) I have an appointment for a blood test on fri as I thought that would be 7 dpo but now I'm not even sure that I've ovulated. Any advice about what to do? My cycle is usually 26/27 days long.
