light period...

okay so the past two months my period has been really light. like lighter than it normally is. like i’m on my third day now and that’s usually my heaviest but there’s barely been any blood on my pad. and i’m just like confused and i don’t know if i should be concerned or not. or if it’s just bc my periods have finally started to regulate themselves out and i’m not skipping a month or two like i did last year or what. so do u guys have any thoughts or opinions on if i should be worried or not?
