Hi Michelle,
I have long cycles - between 5 and 7 weeks. I fell pg this month (on our first month of trying) and I've estimated that I O'd anywhere between day 20 and 26, due to the fact that it has showed up on a HPT this quickly. Sorry I don't have accurate days for you, as I was just gunning it really. With my first child my cycles were 5-6 weeks long, and that resulted in a normal healthy pg too.
Goodluck with everything, I hope you get your BFP really soon!
