sorry to have a moan but I can't talk to any of my friends as they dont know I am ttc. I'm having a really weird cycle this month, got to day 27 & 28 before I got a high on my CBFM, then it went straight back down to low on day 29. My cycles are usally around 34 days so not really sure what is going on? If I assume that I did ov around day 38, then I add 15 days on the af would be due around day 43 ( I am currently on day 35). If I didn't ov then I have no idea when to expect af? I'm really confused and feeling really blue.
