help with the pill?

Rachel
I started taking the pill on the 8th of November, and finished my last period around 6 weeks ago. I now have 2 pills left before taking a 7 day break from the pill but have very painful cramps, is this due to the length of time I've not had my period or should I be worried? (I don't usually cramp until I am actually on my period) thank you in advance!!
