What Causes Vaginal Bleeding After Completing Periods?

Hi,



I am 48 years old and have had regular monthly periods since aged 12 lasting 4 to 5 days. I had my normal period 2 weeks ago but a week after i finished my period i started bleeding again (quite heavily) with at first a feeling of needing to wee all the time (but that has stopped now after a few days) but i am still bleeding. This has never happened before ever and i have no other symtoms apart from looking very bloated after eating even someting very small. Normally my stomach is very flat. I know it could be my age but could it be also something very different? Many thanks
