Mid cycle bleeding a bad thing?!?!?!?

I started spotting on cd17 pinkish, cd18 it had turned to a brownish color, and then today cd19 it has turned to a bright red. It has been very light the whole time. A pantyliner is enough to contain it all day. I have read alot online and talked to alot of people that adviced me that it was probably due to ovulation. I even read online that bleeding during ovulation can be a good thing. However when I called the RE today to discuss this with them I was told that it means that I either didn't ovulate at all or that I didn't have a good ovulation. I always thought and from what all I had read that it was a good thing. Since when is ovulation spotting a sign of something bad. I need advice. Thanks in advance.
