Thread: birth control help?

I have been taking LoSeasonique (a low-dose birth control medication) for a little over 7 months.
I am supposed to have a light period once every three months while on the pill.

During the second month, I started to experience some breast tenderness and breakthrough bleeding. This lasted about a month, and I had my period at the correct time at the end of the third month.
I had an appointment with a gyn soon after, and she explained that it was normal, and I should expect less breakthrough bleeding during the next cycle and even less, if not any, after that.
The next cycle was much the same as the first with about a month of bleeding before my scheduled period.
I'm currently in the second month of the third cycle since beginning this medication, and the breakthrough bleeding hasn't stopped since it began almost three months ago.
I have not skipped a pill, but I haven't been taking them at the exact same time everyday (maybe a few hours apart sometimes). I'm not sure if this would affect me, though.

I'm also taking 88mcg Levothyroxine. My doctor said in the beginning that it shouldn't conflict with the birth control. I don't have another appointment for 6 months.

Is the bleeding normal? If not, what should I do?
