How accurate is the Fertility Friend?

I've been marking the begining of my Period for a year now. I have updated the calendar there, but I don't take temps or anything like that. Do you think the fertility days are accurate that way? Would you BD before and after the identified dates as well?

I've read here it should be everyother day. Should I do it every day on the 'fertile' days?

I knew I would have tons of questions with this!

Honestly charting without temping is really not going to do much for you. FF is not always an accurate software, there is a lot that goes into temping and charting. I would definitely bd every other day up until about 10 days before AF is due since you aren't temping. If there is no male factor issues and you have a strong feeling when you ovulate, you can bd everyday during that short time.
