Your cycles vary a fair amount, but rough average is about 26 days or so. The only way to know for sure when you are ovulating is through blood work but you can get a rough idea, as well as watch for possible physical/emotional changes.

The 14 day rule only applies to someone with a 28 day cycle, which some women do have, but many do not. Even then, being too focused on just a small window can cause you to miss out.

General guide is 12-16 days before your next period will start, regardless of how long your cycle is... but since your cycles are not closer to a regular pattern you may want to go another route for getting a starting place. Taking 18 days off your shortest cycle and 11 days off your longest. Your odds are likely to be increased of conceiving if you are having sex on a regular basis from right after your period ends through about the 19th day of your cycle (day one is the first day of a period). I would even add a few days extra for good measure. Having sex every other day will also increase your odds, although I realize this is not always practical or desired for many couples.

It is important to remember that even with good timing, other factors play a role in conception. This is why it can take many couples a year or so to become pregnant when actively trying.
