Is your period regular or do you have times where you've been late? Lots of factors could affect the length of your cycle (stress, food, lack of rest, etc), so if you haven't gotten either AF or a BFP by now and it's unusual to be late and you don't have any clear reason why you might be so late then maybe make an appt. with your doctor to see what might be up. Let us know how you are doing.
