We have been tryining for #6 for over 2 years now. Im 6 days late now and keep feeling like I'm going to start my period but nothing yet. I have had a major schedule change and diet for this past 2-3 weeks, to where I whent from getting 4 hours sleep to 7 hours of sleep and incorporating more fat and calories to my diet due to the holiday. Could that be the reason why my period is late? Thanks!
