Do you have supply concerns at this time? If so, go ahead and hand express or pump from the other side.
One thing to remember, is that breasts aren't milk jugs. They don't ever get empty. They're more like drippy faucets. Imagine a sink with a really slowly running faucet. You plug up the sink and it will slowly fill and you can dip right into the sink with a glass and quickly fill it with water. Or, if someone pulled the plug recently and drained the wanter, you can still hold the glass under the slowly running faucet to fill it up. It just takes longer. Breasts are always producing milk. So they don't ever get empty.
