EDIT: The title should be "Are moods a comfort test"

My current LTR of 7 months has random mood swings, which I have noticed with most girls in my life. Is this something excusable that I should just allow and continue talking to her or are moods simply a comfort test. I really don't know jack shit about the PMS cycle and what not, but how does TRP go about handling a female's moodiness? If she was a plate I would just ignore her, but with an LTR, do I give her my attention and comfort her even if she's acting bitchy?

Take note, I am new to TRP and have a decent understanding of comfort/shit tests, but I'm unfamiliar if female hormonal mood swings are an issue in a relationship and how one goes about dealing with them.

EDIT: I don't think my question is clear is enough so I will summarize it here:

What should I do when she is moody?
