the 14 day ovulation thing is very misleading- only* some *women ovulate on their 14th day. if your ovulation predictor is telling you 2-3 days, i'd "listen" to it, and like others have suggested, get busy immediately. try to get busy every day for the next 3 days if you can so you are covered. and try to have fun! don't make it a chore :) if it doesn't work this time, its ok, you have next month to try too.
What SGC said.
Anyhow, you're so young I don't see why you're stressing over ovulation, using predictors, etc. Just stay busy getting busy with your new hubz and pregnancy will happen naturally and most likely quickly without you having to worry about counting days, etc. If an old fart like me can do it within one month of marriage it'll be a total breeze for you. ;)
