By FF, do you mean Fertility Friend?

I think if your ovulation date is regular, it is probably quie accurate. However, last month it predicted that I would ovulate on day 18 and I ovulated around day 15/16 going by OPKs and temping. Normally I am 31 days(usually very regular), but this month 29 days. Maybe my cycle is changing? Or possibly just a blip -who knows! This is why I am OPKing this month again. Just to keep a check.

Why not try charting your temp instead? It's free! If you take your temp with a digital thermomiter (sp) first thing in the morning, before you get up, and you monitor your CM you can very accuratly tell when you are ovulating. I used it as a form of contraception succesfully for months before ttc. Google natural family planning for more info.

Yes, but charting temperature tells you after you ovulate (as you get your temperature rise after you have already ovulated) not before, so if you were trying to catch your LH surge (which appears just before ovulation) you would have missed it.

But the egg lives for 24-48 hours so the rise in temp can be a good indication, also if you also chart CM this can tell you when you are about to ovulate because it becomes thicker and like egg white.

Taken from the NFP website:

To conceive
For the normal fertile couple, conception is possible at any time during the fertile phase, but intercourse is most likely to lead to conception on days when highly fertile mucus is present, when there is a wet or slippery sensation at the vulva, and the cervical mucus is clear and stretchy like raw egg white. The most abundant fertile mucus normally occurs one or two days prior to peak day and is a time of very high fertility. Peak day, the last day when highly fertile mucus is present, frequently coincides with the day of ovulation. The temperature shift confirms that ovulation has taken place. At the time of maximum fertility, the cervix is high, short, straight, soft open and flowing with fertile mucus.

Aim to have intercourse during the fertile phase:

When highly fertile mucus is recognised
As close to peak mucus day as possible
