What should i do tommorow?

Tomorrow i am going to confession for the first time since Christmas, just the day after Tommorow i would have reached a new life streak of not gooning, i obviously wanna confess to the sins that still happened after the last confession, yet i confessed doing it during every previous confession and that was always a daytoday thing, but at the same time i dont know if i should really be like: „i masturbated but only for a little less than 2 months after the last confession, since than i didnt do it“, so what should i do? How should i say it?
