Which to trust: OPK or FertFriend / MyCycle?

[CapitalChick]

So...my OPK test showed a surge on Saturday evening (which was surprisingly early!...by several days), and Fertility Friend and MyCycle both predicted ovulation 4 days after my surge, based on about 6 cycles worth of data. Which should I trust?

I would personally go with the OPK. I mean you can continue to BD into the predictions of the online monitors. But all sorts of things can affect the time you O - stress, environment, sickness. If you have a different O time this cycle, the OPK is more likely to show it.

I agreed with Ney

Id go with the opk, so many factors can affect charting without you realising it.

Ack! This is so frustrating. I have lots of ovulation symptoms today (lots of EWCM...I didn't have before!, O-pains, etc.), but I got a + OPK on saturday night and a very + OPK on sunday at noon.
I just don't know what to think!!

I agree with the others ... the OPK.

I chart on MyCycles too and it showed an estimated ovulation date one day later than my Clearblue Fertility Monitor.

there's no harm in BDing according 2 both

I would go with an OPK over charting because the OPK is actually measuring the LH surge in your body while the charting just goes off an average estimation.
