What does your buyer's agent say? Am a little concern that you are asking in this forum and not consulting your Realtor? If you have a loan contingency and you do not have a commitment from your lender it will be wised to consult your mortgage broker or the financial institution that is processing your loan in order to get a time frame. If you only have three days left on loan contingency it would be wise to extend this contingency to be safe. Your buyers agent should be advising you and monitoring all your contract contingencies. Your Realtor is there to protect your interest as your buyers agent.
Best of luck
