Period problems :-( help!

[Mollz]

Im 17 and ever since i started my period at 12 i have always had 28 day cycles that were always on time. Until August 2013 i had a miscarrige at around 6 weeks, since my periods are usually late rangeing from 29-35 day cycles that are really heavy and painful. Anyway March this year i realised my 28 day cycle was back it came April and then may .. suddenly im having a 26 day cycle that is more brown spotting with hardly no blood what does this mean?

I think small variations like that aren't much to worry about (but then again I'm having such ridiculous variations in cycle atm its hard to compare) but a 26 day cycle is normal plus after pregnancy periods can change, of your worried get it checked but it sounds fine to me :3
