Wow, you're lucky that you are ovulating after just one month on Met!! I've been on Met for about almost 3 weeks now and still nothing. But something is happening for sure though , because my breasts are becoming sore. Hopefully my breasts will be sore for over 2 weeks, so I could suspect that I may be pregnant

and I can then thank Met!! But as for now, I don't know what is really happening. My temps have been higher then the average pre-O temps. So maybe I did O and just didn't realize i did. I guess time will tell.
Now, as to answer your question....if you think you O'd on CD14, but didn't bd til CD16...I would say that there is a high chance that you would have missed your egg. Only because they say the high chance of getting pregnant is just before O, and the latest is the day after O. But not 2 days after O. The egg only lasts between 12-24hours.
If you did bd on CD14, but your dh didn't finish his deed, then unfortunately the chance of conceiving that day is very unlikely as well. If u did have an egg on that day, you would need the sperm to fertilize the egg.
