Possible Hormonal imbalance from birth control?

For the past 3 months, I have been experiencing different symptoms that seem like a hormonal imbalance. I have been on Yasmin for 3 years and never had any symptoms. I went off of it for a month, and when I started taking it again I started experiencing symptoms such as: sore , swollen s, little weight gain, mood swings, and hair growth on my face. I am not pregnant, I have had my period every month since and have taken pregnancy tests that are negative. I recently changed birth control to Loseasonique because of this, but is seems that every time after my period is over my start hurting again constantly until my next period. What could be going on, and what should I do?
