i quality bad for you..that must really suck.
as you would expect it can effect a girl's mood..she's taking pure hormones. maybe you should converse to her about it..make clear to her that she's a little moody and you reflect on that she should talk to her doc more or less switching up her meds: either lower dosage or different brand/method.
hopefully she won't go and get mad at you for recounting her that she's moody and kind of annoying you.

It does affect mood. She's taking hormone pills. See if a different type (a lower hormone dosage) would be better for her.

This is not offending - If a woman didn't enjoy periods would they do "it" more commonly?

They will definitely affect her mood. If she go to her doctor she can probably get a lower dosage. Sometimes, birth control pills will do irritability, weight gain, depression and a mess of other problems. She really may be attitude a bit out of sorts and does not really mean to be so irritable toward you. Help her out by going to the doc near her. Help her find a comfort zone.
