I'm 29 years old weighing 182lbs and i'm 5'6. My menstrual cycle usually lasts 5 days and on the 6th day that's when i clean myself up. Last month and this month my period seems to go very slow the first 3 days, to where its brownish on the pad, and by my 4th day it really starts to flow and i am going through more pads than what i normally go through. The coloring of the blood looks normal and i don't have much cramping like i usually do.
Is my menstrual cycle changing because i'm getting older, or could this be something more serious and i should go to a doctor?
I am not on any birth control pills. Would it be better to go on birth control and see if it changes my cycle back to the way it was, or make it shorter in duration?
Any information would be appreciated, thanks.
