Anyone else have this before?

Sarah

I’ve been on the lo lo birth control pill for almost a year now and have ALWAYS gotten my period 2 days after taking the last pill of the pack. So I took my last pill of the pack last night and then today around 2ish this afternoon I started to get some brown discharge but it wasn’t heavy like a period. I’ve never had this happen before. Yes I’ve also have had unprotected sex. Can anyone help with any advice on the situation?
