Perhaps it's a stupid question... I apologise if so.
My first baby was an accident (which is a horrible expression / best accident ever) but now we are officially "trying" for our second. I have no clue about this sort of thing so I bought a pregnancy app. The app shoes the ovulation days. Think there's a window of say 4 days with one being the most important). My question is this...
Does the sex we have on the other days of the month not count at all. Should we not do anything until those 4 days and then hump like rabbits. I don't want to be having sex if there's no point? 
Thanks for any replies....
