I am 6 days late. I am never late. We have been trying for three years well today I took a test and I still haven’t got a positive. But due to my calendar I would be 4 weeks and 6 days if I am pregnant . Had my period twice last month 5 days in the beginning of the month and then 3 days in the end of the month that move towards Jan and that was only 2 days starting Jan. I was suppose to start my period 6 days ago the 29 and nothing. My cycle is always on schedule.
