What is a good online ovulation calculator?

Just wondering what is a good online ovulation calculator. I know you can't always go by those but thats how we got pregnant so quick with our last child.

I found this one Ovulation Calculator | Tools | BabyCenter

It says most fertile from Thursday, June 20, 2013 to Tuesday, June 25, 2013

Then Ovulation Calendar and Ovulation Chart - Fertility Charting says June 19-22

I would probably just use a combination of those dates. My cycle is very irregular so I'm starting to chart temp and use opks, but if you know your own cycle you should be able to predict using those dates. I would probably BD at least every other day June 20-25. Curious why there is a difference in those estimates though. Anyone else have reasons/suggestions?

I don't know about good but I find Fertility Friend is very popular. I use their site for my temp charting.

I always used FF when I was charting. The longer you use it (the more cycles you put in) the more accurate it gets!
