I am on the birth control trinesta. One month I lost one of my packs so I bought a new one. After the new pack was almost finished I found the original one, and confused it with the new one. I started taking the wrong weeks at the wrong time. Since then I have gotten a new pack and been taking it correctly for about 2 weeks. I never didn't take pills (I never took the placebo or stopped taking them because I go straight to the next pack and skip my period once a month.) I just took the wrong weeks at the wrong time. I have had my period for over 4 weeks now. What does this mean and what should I do?
