My periods are start at the end of the month and ends in the beginning of the month. My period last for 5 days. Well today I had really light blood in my panties. So I put a tampon on. Well when I took it out there was really dark brown discharge or whatever it is. Its was so sticky like glue the tampon didnt even absorbed anything. I know it sounds gross but i touched it and it was extermly thick and sticky...there was no odor. What does this mean? Can it be im going to start my period soon? Can I be pregnant? Infection?
