I have a real crappy chart this time around. I usually don't have a temp on Sundays, now it looks like more than Sunday. ANYWAYS. My question is....my periods are 28-30 days ALWAYS. The last chart I have I O'ed on CD16 got PG then had a M/C around 7 weeks later(

). That chart was more informative. Since my cycles are 28-30 days, Do you O on the same CD as the chart before? Will it vary a few days before or after te last chart? I BD on CD14, I will tonight (CD15) and most likely the next 2 days. I'm just trying to "catch" the day I O.
(Sorry if this sounds confusing, but when I wrote it and said it out loud, it made sense.

)
