Faint positive 3 days before start of period spotting day period was due next day had 1 day of moderate bleeding WA lot of dark brown blood at the end of the day is this implantation bleeding?

I had a negative test 3 days before period was due, then two days of spotting exactly like you describe on a Thursday and a Friday...on Saturday I got a positive test. I spotted through my entire first trimester and had a wonderful pregnancy. That baby just turned 2!! Wishing you luck!
