Extended periods

Heather

So- I started taking BC pills for the first time in more then 10 years- well- I started my pills on July 7th- first day of my period. It’s been 13 days- I am still spotting and it’s a darker brown/red. I never had any real “heavy” days. Sorry that this seems stupid- I just haven’t used pills for so long- I have no idea if it’s normal/not normal. Also- it is helps- it YAZ. Thanks for any feedback!
