No pill in time

Due to insurance reasons I won’t be getting my birth control on time to start my new pill pack. I’ve been wanting to get off of it for awhile but have been scared for reasons such as acne. I do have one pack of generic brand with the same dosage as the one I’ve been taking, it’s just not the same pill pack at home. Any advice? Should I just try getting off of it or should I take the generic similar pill
