Is possible the transaction will be dropped. Then it's like it was never sent.
I think its usually when not confirmed within 48 hours (or maybe 72... I'm really not sure about this)... but it seems it's being rebroadcasted ( as you said it was 3 days ago).
You better make some snapshots (to have some proof you should receive this payout ... just in case the sender will try to fool you)

As receiver can do only the 2nd option. This means send those unconfirmed bitcoins somewhere else with higher fee (but that will cost you additional fee, I think you do not want to do that).

Better to try the via accelerator (in the second one this tx is already listed )

Which wallet you are using? Are you sender or receiver of this transaction?

too small fee + overloaded blockchain = very long time to confimation

Options you can do:

1 - replace by fee (search for more info)
2 - child pays for parent (search for more info)
3 - trying some accelerator https://pool.viabtc.com/tools/txaccelerator/  or http://confirmtx.com/  (due to small fee i don't think that will work)
