Im trying for baby number 2 and wondering how long did it take you ?

its been 6 months of trying nearly 7 months now and no luck maybe this month but prob not i have no idea why this is so hard to happen as with my son first month and bang pregnant the first time ! im using opk and conceive plus lube taking pills and trying everything in the books and im having fun along the way in fact im heaps relaxed about it now as i don't think il get pregnant so im not over stressed when AF comes
