Spotting for weeks in early pregnancy!

As of today I am 6 weeks. Basically since I found out I was pregnant at 4 weeks, I have had spotting!

Week 4 was very light + intermittent.

Week 5 has been a little heavier, but not enough to stain my pantyliner. I normally have a little spotting with every wipe. It’s light brown, dark brown, VERY occasionally dark red or light pink. Sometimes tiny clotty bits when it’s dark brown. :-(

ignore the CD’s - taken over the last 1.5-2 weeks.

Has this happened to anyone that has gone on to have a successful pregnancy?

I have had 2 prior miscarriages that have started with spotting, but it turned to bright red blood within a week!

My tests keep getting darker! They are now always darker than the control.
