Was your account pin verified? Was your finalized earning above $100? If yes so please send screen shot on PM of your payment page with hide of your identity. I will guide you batter.
Pakistan was also included in receiving payment problem this month (payment declined) , do you see payment declined on your account? Thanks
see here : http://productforums.google.com/forum/#!category-topic/adsense/payments/uvH1nce1sN8 looks like same problem occurred this month too.
I think you shouldn't worry, i got payment last month earlier than most of the publishers, You may check the last month's thread when i posted that PI in Pakistan, no one believed but i think it's happening that some getting early and some late.
