It doesn't affect my anxiety, and I'm not depressed (give my therapists more time to achieve that, though ). But I would know when the thing was coming because a few days beforehand I would get all emotional. It only lasted half a day, but when I find myself weeping at a Budweiser commercial (the horse and his trainer one), something's up.

I don't currently experience periods because of the medication I'm on. Can't say I miss them.
