odd 'periods' after 2 years

[StarShine94]

Okay so it's coming up to the two year mark now and recently my body has just been weird. Last period I had was in November and was heavier than normal, since then all I've had is pink and brown spotting here and there, usually every 1-2 weeks or so.
Has this ever happened to anyone here?
I would put it down to me moving in November but recently I've been really moody, having a sore lower back, headaches and twinges here and there in my lower abdomen

I'm assuming you've taken a hpt?
