We have decided to start trying for our second child after falling unplanned with our previous, so I've never had any experience with the "trying" part. My question is will I only fall pregnant when ovulating? Or could it happen any time throughout the month? The reason I ask is I'm pretty impatient and not a huge fan of the "act" (more usually too tired and can't be arsed to do it) so want to know if it's worth lying back and getting on with it or working out when I'm next ovulating.
