After having my son prematurely in summer 08 I went back on the pill.

I stopped taking the pill 6 months ago as my periods were starting to get heavy and painful again.

This month my period was uber heavy and painful, and though I finished my period 6 days ago, I still have period pains, bloating and am extremelly tired.

I'm in my early 20's and this has never happened before, although I've always had heavy and irregular periods

I don't know if this is normal or I should see my GP. Any suggestions or explanations would be great thanks:
