Where are my bitcoins - unconfirmed transactions
The transaction d3f86df12c12801ca97244a773287226fd1e833e7151b1ab3a90bff930351e50 has a zero fee, so I doubt it will be confirmed anytime soon. Do you know how to double spend it and specify a higher fee? 

The other two transactions also have a very low transaction fee but that would still be OK. The problem is that they are spending from the zero fee transaction. Therefore they cannot become confirmed before the parent with zero fee is confirmed.

You say that you sent those transaction a week ago, but Blockchain shows that it received them yesterday. Maybe they were dropped from the mempool after some days last week and now your wallet did just rebroadcast them. What wallet do you use?
