I have light spotting with long blood clots prob the size of a pencil in length. It would stop . Then my husband and I would have sex then I would starting again with long clots... before this didn't have a cycle for about 3 or 4 months. We are trying to conceive.

I would see a Dr. if I were you. Better now in case it is something that may be unhealthy and/or stopping you from getting PG.
