HI ALL PREGNANCYS ARE DIFFERENT. I HAVE 3 CHILDREN AND ALL THE PREGNANCYS WERE DIFFERENT. THERE IS A HIGH CHANCE OF PREGNANCY AND IT COULD DEFINATLY BE IMPLANTATION BLEEDING. I WOULD TAKE A PREGNANCY TEST TO PUT YOUR MIND AT REST. IF ITS NEGATIVE MAYBE ITS THE START OF YOUR PERIOD. IF YOU STILL DONT GET YOUR PERIOD THOUGH I WOULD TAKE ANOTHER PREGNANCY TEST . I HOPE THIS HAS HELPED YOU. LET ME KNOW THE OUTCOME, ALL THE BEST TO YOU.X
You could be, you never know and yes brown blood is common around time of your period. Since your period is due take a HPT! Your symptoms could be pregnancy or even AF coming but late.
