Weight gain in pregnancy

During pregnancy the expected weight gain is about 11 kg. I still have few months to go and I have already exceeded that by 2.5 kg having gained 13.5 kg.

Should I be worried? I am actually trying to maintain a fairly balanced diet but, each week I am almost certain another kg will be creeping up on me.

The picture of Kim K below does give me hope. Anyway I guess I should look forward to shedding the weight after delivery. Fingers crossed!!!
