Hi M,
Here is a link to my chart when I concieved Violet http://www.fertilityfriend.com/ChartGallery/16281.html

We weren trying for a girl but it turned out we couldn't BD closer to O... even tho I was wanting to try for a boy #-o . I suppose I should've used a condom... oh well.

A couple of things... one, I would keep an eye on if your have to go through another cycyle is your CM, I found this a great indicator to when I was close to O. I knew I was close to O from my cm when we BD in the above chart, but didn't think I was close enought to conceive. Two, I would use OPKs if you aren't 100% sure of your upcoming O day, and don't BD when you get a +.
