For the past 3 months have had 2 periods a month ( not normal) that last a full 8 days (normal).
But its not the same it almost looks like its has more blood less of the other stuff, but still just as heavy.

You need to get your iron checked. You could be anemic and you might need to take an iron supplement to bring your iron back up to par. If this IS the problem it will not go away until you take care of it. My wife had / has this problem and if someone (particularly her ob/gyn) had told her to get her iron checked, this would have prevented a HECK of a lot of problems and trouble. Don't just get the iron quickie test, get the in-depth iron test to make sure your body is getting what it needs.
Good luck.
Cheers.
