Fertility Friend accuracy (chart LIP)

[simpsongal]

This is my first cycle of temping.  I just put in today's temp (98.6) on CD 15 and fertility friend updated my calendar & chart, showing a predicted ovulation day.  It says I O'ed on CD 10 (98.0), which seems about right based on temps and my 25 day cycle.  But I've had a somewhat gradual temp shift, so I think there's room for error.

In your experience, how accurate is fertility friend at making predictions?  I'm a little anxious about it b/c DH and I were pretty lazy this month - by FF's estimate we only tried once this cycle (the morning before or the day I O'd).

ETA: made thread title a little more specific

Is it a solid red line? I've only had 1 cycle out of like 25 that I think FF was wrong on my O date.

Can you post your chart? Are you using opks?

[simpsongal]

I used wondfo OPKs, I only got one solid line on CD 10 - I got a couple faint lines before and after but I just recorded those as negatives. I'm also wondering if I'm realy 5 DPO.

How do you post your chart?

Basically, it is as accurate as the info you put in, and gets more accurate with the more info you have. FF does change its mind sometimes, so you usually need to get the whole cycle charted to see the big picture, especially for the first cycle or two.

eta: To post your chart, go to the sharing tab on FF.  Under charting homepage, check your setup, then get code.

*poof*
Let's see if this worked.

I think the link is working.  I wish I had more data to input, but I had trouble observing CM.  I appreciate the input.  I know it's early in the process for me, I just want to make sure I'm doing this right.

CD10 is a possibility, so is CD12. It does look like you have a temp shift- you may need a few more days to really confirm. Dotted crosshairs means FF is still unsure.

For the wondfos, a positive is when the test line is as dark as or darker then the control. Is that what yours looked like on CD10? Faint test lines are negatives.

eta:  I think you are doing fine.  With the first chart, you don't know what to expect, so it is confusing.  Once you have a month down, you will know about what your pre-O and post-O temps are, and what a completed chart looks like, and that will make it a little easier.

Thanks radishes - if my cyce is consistent, this chart makes me feel better about cycle 1 - we were definitely 2+ days late TTC. The OPK line was as dark if not darker than the control. I remember being struck by the difference -- like, "that's what it's supposed to look like."

I thought I o'ed on CD 12 but I don't know - I think FF is being unduly influenced by the +OPK. Thanks for the tip about the dotted crosshairs - I didn't realize that.

ETA: It's really cool to see the temp shifts - I think you aways go into something like this wondering if temping will show you anything.  DH was really skeptical about the spike after O.  (Considering teaching this to a daughter one day).

It looks like it could either be day 10 or day 12. Sometimes, I think it's impossible to tell until after it is all said and done (especially if you have a critical day where you wake up late or have a wonky temp for some reason).

[ilikedonuts]

I think it was CD12. I bet with a few more high temps FF will shift it.
