cervical question

Hi I would like to know if someone out there have a pea sized hard bump on their cervix? Since I started to chart my fertility with the checking the cervix. I have been feeling this bump for more than 3 months now. I can only see the gynecologist in july...he's very busy. But anyway, could this be a cause for concern? I would also like to know how to feel if the cervix is open or closed. I missed my period on january but came very late in february. Mosty brown/dark blood. Only one day was bright red blood with tiny blood clots. Just now I wiped and its very bright red discharge with tiny blood clots. My "period" ended yesterday
