I tried to refill my prescription but the pharmacy said that I don't have any refills left but will ask my doctor for the confirmation to continue it and I should be able to receive my next pack of pills by Tuesday. However, todays is thursday..meaning I'll be missing 3 days of the pill. I'm a Sunday starter. Does that mean I continue taking the pill on that upcoming Sunday or do I have to wait for my next period to continue with the pill?
