Weird spotting


I’ve had a few faint positives, however I have not had a chance to go to the doctor yet. This evening I noticed some rather weird spotting...more than light pink but not red...somewhere between light pink and light brown. There were small, tiny red pieces on the toilet paper though...I hope you know what I mean by pieces. Not clots, but maybe like tiny, tip of a pencil size clots. Not a lot at once, just a couple here and there. No cramping at the time of spotting but I have been cramping a lot over the past couple of days. Should I be concerned?
