birth control
"I have just taken the nuvaring out (cannot get hold of doctor until monday) as the first month on it I found my mood changed. Got very angry arguing with my SO and blowing up over very minute things. Thought I'd try for a second month but within 2 days I found myself emotional waking up crying for no reason irritable depressed.  So on my day I will go back to the drawing board with my doctor. Apart from the mods I've had no other symptoms but the are too server for me to deal with."
