Beata, so interesting that you thought you O'ed on day 13-15 & its confirmed as being day 17. Hope you and DH are going for gold now you never know. I think a lot of people must do that, think they O within a particular time frame and get it wrong. I have a great book by Zita West (she is like a naturopath I guess, specialises in helping women get pg & preparing those for IVF who need to go down that road) who says that a lot of women she sees make incorrect assumptions about when they O, its quite common. I didn't know much at all until I read her book. I guess trying to get pg can be much more complicated that you would first think. I hope DH's police check comes through soon, don't they know there's a little bubba waiting!

I will certainly let you know about the AP. I have read lots of great things about it too!
