numb, confused and sad

Well I went for a jog and met my husband and son at the nearby play ground. I had to go pee very very bad so I went in the porta potty. When I pulled down my pants my panty liner was covered in blood. A dark thick almost pasty blood. I'm assuming I'm m/c. It may be implantation bleeded. I did have that with Ian but I don't remember if it was this much. I'm torn on what to do now. There is nothing a doctor can do. If I would have waited like I should have I wouldn't be going throw this. Is there a glimmer of hope? Yes but barely. The next 24 hours will give me the answer to what is going on.
