Q: My paper is not published even 2 weeks after the proofs were ready. What should I do?

My paper was accepted by BMJ Case Reports, and it was to be published after proof. However, there is no progress for 2 weeks, though for my previous submissions to teh same journal, it was published within a few days. When I checked the journal homepage, no case report has been updated in the last 10 days, though usually more than 10 reports are updated each week.

I assume there is some problem at the journal end, but should I make an inquiry to the journal? Currently I have another paper at this journal which is under review, and I want to take action as soon as possible. If it would be better to withdraw my paper and resubmit it to another journal, I will do so.
