I am now 4 days late and that is very uncommon for me. I am usually on the mark when it comes to being regular. I have taken 2 pregnancy tests and both came back negative. I have been extra tired, nausea all day, tender breasts. This is the first time this has happened to me. With my other 2 children I tested right away. I am just not sure what is going on.
Are you stressed? Your period could be delayed because of that. The only way to be sure is if you go see your doctor and get a blood test.
