I don’t think anyone can (or should) answer that for you, if you are unsure, then the best thing you can do is go to confession and either confess it, or just ask about it,
remember that even to confess your temptations in confession gives you the special graces you need to gain power over those temptations, so even though you are unsure, you should definitely go to confession,
just keep in mind, God knows we are weak, and He is there to help us because He loves us so much,
so when you fall into sin, don’t think to yourself, “what a hopeless miserable sinner i am” and then fall into despair, but instead say to Jesus, “See how weak i am without You? please give me the grace and strength i need to fight and flee from these sins” or something along those lines,
we are weak to sin, but we must not despair, because that is contrary to humility,
even if you struggle with impurity, you can still have strength and find confidence in humility,
we are sinners and we fall, but Gods mercy if far greater than our sins, so we have alot to hope for in His mercy,
so anyways, i would definitely recommend just going to confession, because even the church tells us, “when in doubt, by all means confess”
ok, hope this helps, take care.
