Where are my bitcoins - unconfirmed transactions Using Bitcoin Core wallet, I sent coins to an address of mine outside of the wallet. All three transactions sit as unconfirmed though show in blockchain.

they are the bottom three transactions. Not sure why they are showing as "spent" - I did send about 0.65btc to this wallet after which I then spent.

So in short - the bottom three transactions are showing as unconfirmed on BitcoinCore, the btc is not in the account they were sent to. Where are they?

Further info - the bottom 2 of the 3 transactions were sent almost a week ago though didn't show up in blockchain until I reinstalled the wallet app. However, BTW is still nowhere to be found. Fees - bottom two were sent minimum, top of the 3 was sent as recommended and all are showing as "0/unconfirmed" in the wallet app
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?
