S.B.
I have been on the pill off and on for years. I have always been told that break through bleeding can be normal the first few months as your body adjusts to the new hormones. My doctor as always asked me to give a new pill three months if possible.( It helps to take the pill at the same time each day.) Most of the time that seems to "cure" it. One time, I felt like I was on my period constantly...I don't think I even made it two months on that pill.
Personally, for me, loestra fe worked great for me the first time I used it. A few years later, I was put back on it. It didn't work for me that time. If I took it at the EXACT same time each night, I was fine. If I missed the pill time by even an hour, I had break through bleeding.
I would put a call in and talk to your doc or a nurse. Just to see what they say. They may want you to continue with that pill. If you are really uncomfortable, let them know. The nice thing about the pill, is there are many, many to choose from. If this one doesn't work for you, another may.
