On every single period I have, I'll have the normally weekly period (lasting 4-8 days :/ ) and then I will stop bleeding and have brown blood (almost unnoticeable, I know that's normal.) and this will continue to happen for either half a day or a full day, then I will start to bleed for a day or two like it was a normal period! It really does suck because I will take my pad/tampon off, but my period will start back. Why does this happen, and how can I avoid it?
