I did not like the bleeding so we called the doctor and she said it was normal and gave me medicine for the bleeding which eventually stopped it. 

In my 3rd week of the pack, I began to experience nausea and brown/red bleeding (had to use tampons).The nausea stopped within 2 days, but the lightish bleeding continued for about 5 days. We also called the doctor about this because the delayed nausea really made me nervous about pregnancy. The doctor said the bleeding and nausea was normal. She perscribed me medicine incase nausea returns. I asked if I were to still have a period this month and she said yes.

I am now on my first white pill... last night I had light cramps thinking my period was going to come today, but did not. Also breast are slightly tender as if I were about to start period. I am also slightly irritable.

I am curious as to how I'm going to have a period after all this bleeding or if that last bleeding was infact my period coming early this month? I don't believe I'm pregnant since we used such procaution, but could I be? Is it normal to NOT have a period the first month of taking this BC? Has anyone else had these weird delayed symptoms such as nausea and bleeding?
