3 periods

Kirsten

Hi looking for some advice I have had my period 3 times in one cycle :( this isn't Normal for me I had consulted the doctor an she had said it was just old blood an it was normal? I don't feel this is the case though as it is the exact same as a regular period for me. Does anyone have any ideas on what it could be I am on holiday atm so can't consult a doctor again until I am home.
