Trim stem = pain?

I’ve never had any pain with my Lena cup. I decided to trim the stem because I definitely want to keep it, but not the original length (it was too annoying). So I trimmed it last night, just one notch away, and put it in overnight. Ever since I trimmed it I’ve felt a slight pain/discomfort whenever I shift positions or sit up. Did I do something wrong?
