I have been on orsythia for over a year and lately i have been experiencing some weird changes. First, my period started a week before the sugar pills and lasted untill i started my new pack. Then i felt that my breasts are getting sore, and i started getting headaches and dizziness. I feel weid pressure on the right lower side of my stomach, and a few days ago i started having cramps. I have been taking my pills on the exact same time each day and have never missed one. What is happening?
