Ca trim mym oustache during Omer?

Question

My Moustache is getting very long. I do not keep a beard and my moustache is curling under my lip into my mouth. I trimmed it very short before Pesach but it is very long now. I have to admit I never realized I trimmed my moustache more frequently than 25 or 26 days now. Must I wait until Lag Ba'Omer or am I ok to trim now? Thanks, Ben
