I would wear it as you've been advised to wear it.
Make sure you're not washing it in hot water, as this can affect the shape - wash only with cold water. Also wouldn't drink hot drinks with it in.
Don't drink soda or juice with a retainer in - the sugars in both will get trapped under the retainer and bacteria will breed and basically you're creating a greenhouse for bacteria and tooth decay. You should always clean your teeth before putting your retainer in and then drink nothing but water when it is in. This is easy if you just wear it at night.
Check the retainer and make sure there isn't a crack in it, as sometimes cracks can happen - especially if you grind your teeth in the night (I'm already on my 2nd retainer, after 3 months, for that reason!). Cracks can affect the retainer's ability to hold your teeth in place.
Otherwise, just talk about it with your ortho at your next appointment.
