ovulation calculators

hey ladies,
have been using ff for the past 9 months or so. I haven't really taken my bbt in the past few eeks (we're moving and it's been stressful) according to ff, my fertile days are 7/7-7/13

i looked up some other ovulation calendars and got completely different results:

webmd (which is the one i went off of three years ago when we conceived ds) 7/5-7/9 with a 26 day cycle

babycenter 7/5-7/10
1st response: 7/5-7/9 (26 day cycle)
7/6-7/10 (27 day cycle)

etc etc

which would you believe? FF or the other calculators?
I'm afraid I missed my chance because i was going by FF!

thanks!

I'd say FF since you've been tracking previous cycles with it so it kind of "knows" you and your LP already. The other ones are probably just based off of a 26 or 27 day cycle w/ a 14 day (average) LP.

Ovulation calculators are not accurate. I would say stick with FF but even that since you have not been temping is not going to be accurate.

Maybe start using OPK's like tonight if you can? If anything, just BD every other day.
