Skipping a dose or not

So I asked my doctor to let me go back to 7.5 because 10mg is making me miserable (vomiting alot, fatigue, constant nausea) and I never had anything more then Sulphur burps before. She is willing to drop the dose, but said my insurance won't cover it until it would be time for a refill. I have 1 more shot of 10mg. Do I take it or skip the week and wait for the 7.5 to be filled?
