Answer
Since you did have a period (even though it was three days late in starting and lasted 4 days, you are not pregnant, especially since your pregnancy test was negative. A period is normal as long as it is less than 14 days of bleeding. It can even be only  one day. The earliest signs of pregnancy are breast tenderness, fatigue, and nausea. However, fatigue and moodiness can be due to many different reasons. If you have any doubts, take a blood test for pregnancy and you will know for sure.
