im pretty sure there is no consequence in taking 2 bc pills in one day, as i have done it myself by accident.
I too have done it.. I don't think one extra pill will hurt you. Better safe than sorry.. right?!
Why are you not able to look at the days markings? It should be marked clearly for that purpose. You need to get another container so this does not happen to you again. But I have only doubled on them that is if I missed one the day before not when I was regular and I wasn't sure if I had taken it for that day ask your doctor because the pills come in differnt strengths and could affect you differently than other people.
The pills I used to take would have you double up if you forgot one, so probably if yours are like this, you're fine.
