I have a lump inside my vagina, since giving birth 9 weeks ago I had a period for 5 weeks then I was off for 3 days then back on for 1 week then off again for 4 days now I am back on, at the beginning of this period it was really dark brown close to black and it was blood not discharge and I have noticed about 4 days ago that I have a biggish lump inside my vagina at the front and its not been there before what could it be :confused:

After giving birth you will bleed for some time. No one ever tells you that when they are sharing their birth stories - do they.
But bleeding is normal.
As for a lump, I would call your doctor tomorrow and tell them.
