I do not use opks or track my temps (due to different waking times) so I rely on my body signals and ovulation calendars. Ive been using online calendars and they have told me different days when i am likely to ovulate: 25th, 26th and 27th. My LMP was dec 13th and I have had O pains all day today. not sure what to think???? ALSO... I BD last on the 24th and will not be able to do so again until after the 27th (latest O predicted date) does anyone think that I will still have a chance this month ? argh! confused !!
