Not Not Trying? Newbie, Confused

So my husband and I have stopped using contraception....and then I found this app, lol. Opened a whole new world to me with so many questions. :::Naive::: So the percentages are they normally in the low 30% range or do you ever get a majority 75%^? Also I don't want to obsess because I feel that will cause stress? We have the mindset 'it will happen when it happens', but should I be logging my every move? Help, anyone in my boat?
