I think I have spotted but im not sure..

Last month, November 10-14. I had a period. And it wasn't like any other period. The color was dark (sorry for the TMI) and it has never been like this before. Im a 30 day cycle. Now, on the 13th I started to see somewhat a brownish color with a tint of pinkish red color. But it was only when I wiped. It never even once got on a panty liner. Ive cramped just a little but nothing major. I got up this morning to go and pee and there was nothing. Me and my husband has been trying to conceive for 7 months now. Can someone please tell if they have ever done this and/or what could this possibly mean?
