Emotional when on BC?

I've been on nuvaring for some time now. Honestly, consistently for 6months and before it was bit off and on. And now that I've been on it consistently I'm recognizing the side effects. Nothing too major but I'm having CRAZY mood swings (Like crying over nothing, ALL THE TIME). I can handle (breast tenderness, not being as wet down there) but this crying thing is driving me nuts! I'm so emotionally sensitive all the time. I cried - no joke - 6 times in one day. Literally over nothing (it was before my period but does it matter since I'm on birth control?) like I didnt have the cereal I liked. And I'm not a teenage girl. I have a job and pay my bills! Like I shouldn't be crying all the time about nothing! Do anyone else have similar problems??
