When did your period start - before or after you stopped taking the Pill? The average non-Pill period is about 5 days, I think, so you may be at the tail end. What are you taking for the pain? If it's not helping, I've just discovered that you can buy paracetamol and dihydrocodeine over the counter at Boots (even stronger than paracetamol and codeine) and it made a difference to my period-affected weekend!
