... post partum check up. This is my first time taking them and I've been on them for about a week now. However I did not start on the first white pill of the pack or on a Sunday. My doctor said to start as soon as I pick it up. When I started, it was a Saturday so I took the first pill that was marked Saturday which happened to be the last white pill and then I continued to take them through the light blue pills. Did I do something wrong? Is it okay that I started where I did?
