Thursday (March 10th) I noticed a little bit of pinkish discharge. I have been using liners since. It continued all day, it was brown at some points. Yesterday (Friday, March 11th) it started off the same way, and every time I went to the bathroom (which was A LOT) it changed. One time it would be light pink, barely even there. Then it would be a light brown, then dark brown, then start a little bit of reddish brown, then it would be very red. Last night before bed, it was a light, light red. Today, it started off bright pink/red. Now it is a little brown. Could this be implantation bleeding or something else?
