without temping, peeing on sticks etc? no sign of pg despite dtd albeit not that often at ' fertile' time. We do already have dcs, and were leaving this to fate but its just not happening. so is there anyway of telling? Cycle is standard 28 days but I spot for a few days before (sorry for tmi ). Am I calculating dates wrong? I am happy with what I have that goes without saying but feel bit sad that that's it. Don't mean to sound ungrateful, I know I'm lucky..
