You are able to view all of your placed and received bids once you are logged into your account.
Connect your wallet to sign into your account.
Click on the "Bids" button (located up the upper right-hand side of your page)
You can choose to view "Your Bids" and "Received Bids"
You will find all of the bids you have placed under this tab. Next to each bid you are able to view the status of the NFT you have bid on. It is a good idea to check this tab regularly if you are actively bidding on an NFT, just to make sure you don't lose the highest bid.
Under the received bids tab you are able to view all of the bids you have received on your NFTs.
