Ok, long story short. I generally O on CD15, with an 11 day LP. Well this month I O'd on CD13 and am at 11DPO today. I read somewhere that your LP doesn't generally change. I'm confussed and don't know weather to say AF should arrive tomorrow or on my original predicted day of the 31st. Any advice would be very much appreciated. https://www.fertilityfriend.com/home/db094 That is my BBT chart if you would like to have a look. Thank you! to all TTC!
