Implantation or super light period!?

Charlotte

hey guys I really need some help

I'm on holiday! *yay* but having a super strange period.

very little there, but enough that I can put a tampon in. it never fills up though.

it was dark red at first but really light with (sorry) bits in, now it still light no bits in.

I'm really worried about my health my periods are often irregular but never this strange! help!?
