My menstrual cup is pms'ing

I'm so I have been using the same cup it's called a Luna since march no issues or leaks but this cycle(started yesterday) it's had been being a bitch I know it's opened I feel it pop and I do exactly like a always do but for some reason today it wants to leak. And it's not residual from what in my vagina walls, it's a slow steady leak, yes I'm wearing a cloth pantry liner just in case but still.. it's annoying. Had this happened to anyone with their cup? For months it works perfectly fine and does what it suppose to do and then one cycle it's like nope not gonna happen.. I don't know maybe it's my body saying give it a rest for a cycle..
