A question about the pill?

Okay so i tried to be clever and take two packs of the pill to skip a period, i've done it before when i was on a different pill and it worked but this time i'm on a different one. So i thought it was working fine until 3 days after i would have been due on i came on anyway. So i've carried on taking the pills thinking it would just be a light one and only last a few days but it has been the worst period of my life! I've had like contraction pains (i've had a baby so i know what they are like lol) everyday for 6 days now and it doesnt seem ready to be over yet. So my big question is should i carry on taking the rest of the pack of pills and have another period in about 2 weeks or stop now and carry on whenever? I don't know what to do!? Thanks!
