I swear I'm smart!

Really. I'm smart. Or at least mostly smart!

I used a few different online ovulation calculators. The dates they gave me are all way different. Any idea why that might be?

One site (web md) says February 13th to the 17th.
Another one (countdown to pregnancy) says February 10th to the 14th
And a third one (babycenter) says February 11th to the 16th.

I suppose the smartest/safest thing would be to use the whole range (the 10th through the 17th) as the fertile period, but why the discrepancy?

I used those for one month and found them to only be accurate if you have a 28 day cycle and always ovulate 14 days before AF arrives.

Charting has been very effective and told me all about how my cycles are shorter than I thought, that I ovulate later than I thought and that I have a LPD.

Now, each month, I know exactly when I ovulate. More importantly, I know something is wrong with my cycle.

Good luck!
