TMI PIC Heavy bleeding and clots ttc

I'm trying not to get my hopes up, but could heavyish bleeding still be implantation bleeding? It went on for two days, is dark red with clots, and mixed heavily with a type of cm I think. It is not like normal period at all. In fact, my period is not due to start until 6/5, and this started 5/30 (6dpo). So now I am confused on the whole matter. I have researched everything I could find in Google about it but came up with very little. Even if it were an mc, it only lasted a short period and was lighter than my menses normally. I have read that cp generally are heavier than periods? I also have not had cramps during this strange implantperiod, so I am just lost. I had cramps before the implantperiod. It was a sharp pain down my right side. I have thought that maybe it could be ep. I just don't know. I'm scared to test because I don't want a false positive if I lost it. But then, this mini period acts like a little of all these things. I can't pin what it is because it seems to have characteristics of many things. I won't go to the doctor for it, because I  want to make sure it's something serious first. Please help ladies. If you have the same thing, or had, please share your story and what happened in your ttc. I will update the thread with my results as well when I figure things out.
