Please help

Hello,

I started the pill months ago and have taken it frequently and properly. However, I started a new pack the day my period started (November 18-21) which was one week ago and this week I noticed brown discharged and a little spotting. No cramps associated with it. I’m on Novynette and I have PCOS. I’m not sure if this is normal or if I should be concerned.

Keep in mind I had sex a few days after my period (23 November), the same week it ended.
