I need your help!! Do I edit this word out?

One of my beta readers has brought up a concern with my TWISTED manuscript and I’d like to discuss that with you today. “Ragging”: not the most pleasant word no matter which way you look at it.

Wikipedia suggests… “Ragging is a practice in educational institutions… that involves existing students baiting or bullying new students.”

That is not the term I am referring to here now. Consider the “vulgar slang” version of the word.

UrbanDictionary.com suggests “ragging” is: Menstruating. i.e. when a woman has her period. The origin is possibly from the days when women had to use rags as sanitary towels.
“She’s always moody when ragging – she’ll be better in a day or two.”

 BAM!! That’s exactly what I’m talking about.
First off, let me give you the scenario. This is an excerpt from Chapter Four of my TWISTED novel, when Abigail Jenkins realizes that she has caught feelings for her ex-boy toy and current housemate Edwin Santora. I’ve highlighted the sentence in question.
