S.K.
I was on the nuva ring after my daughter was born - i found it helps w/ the mood swings b/c the hormone release is more even through out the cycle (same thing has been said for the patch) - vs. an actual pill - has to go through your digestive system, then once it is digested - the hormone levels spike and then wear down as time goes on and it at it's lowest 24 hours later (when you'd be ready to take your next one). try taking your pill before you go to bed - so hopfully the hormone spike will mostly be while you're sleeping - and be a bit more level through the day.
