Why is it getting lighter?

There was one that was darker and now after it keeps getting lighter. Why could that be?

I don't know how many days in my cycle I am because I never really got my period. I had a polyp removed and my uterus cleaned out on the day I was supposed to start. I think the next day I had some dark bleeding but it was only in the morning and that was it.
