My first took 18 months!!! My second was a surprise baby, conceived during my first postpartum cycle (my baby was 8 months old, condom broke). My third was another second cycle surprise (my second baby was 2 months old, and I was on the pill). My fourth took 3 months of trying (my third baby had just turned 1). My current was a surprise after trying through 2 irregular cycles and deciding to wait another 6 months (my baby was 7 months old). I think it's much easier to catch when you aren't trying but aren't preventing.
