Normal periods until this month
So I had normal periods all this year and now this month my period started on the same day but it was pink when I wiped then it turned brown. I got my period the 3rd day finally but I only had the period in the morning 11-12 then I barely had one throughout the day and night (it would be brown if I had anything). This has still been going on and it's the 5th day. Is my period just irregular this month?
