Bleeding too early

al

I have been on birth control for 14 years. I stopped it to get pregnant. Now have been back on it for a year. I am on Tricira Lo 28. The last two months I have gotten my period a week before sugar pills. Then still get my period the following week although it is light. I am so confused. Never miss a pill, and haven’t ever had problems before. Should I get off this pill?
