as the title says really, does everyone find it to be pretty accurate with ovulation days, or does it move yours around alot?

this is my first month using it, so not sure whether to believe it or not! My temps are consistent with ovulation on the day it says i did but not sure about my CM. lol

Since its your first month charting it may not be entirely accurate, it usually compares with previous charts to get the best results for you. Youll find the more months you chart the more accurate it will become.

i've found mine pretty accurate although now my temps aren't in line with my cbfm!! When i was just getting the hang on cm i didn't input it as i was clear which sort i was having and didn't want the chart to be wrong cos of that.

yeah, the more data you input the more accurate it will be. FF moved my O time a lot and it frustrated me, but I think the best interpreter is yourself I think temping and cm watching are both good tools. I am too nervous to check my CP BUT I think my last cycle FF might have been close to when I O'd and I fought it big time. I thought I O'd sooner, but then a few days later I had CEWCM (FF moved my O~time to that day) and I was like, dang-it! since I was out of town and away from my darling DH

This is my first month of actually Ovulating on FF, previous cycles made no sense because I wasn't ovulating....

Like AG said, the longer you use it the more accurate it becomes

thanks, you've all been really helpful!

It got my ovulation day wrong this month, said I ovulated on Bank Holiday Monday when I know, from cramps and general feeling, that it was Tuesday, so I had to play around, tweak it, manually change it. I only did that yesterday and the frustrating thing is it's moved me back to only 13 dpo, which was common sense but no less annoying.

It gives a general idea but, I would go by your own body and just use FF as a reference. It is not foolproof.
