My period is has always been like clockwork since starting the pill. I usually get it 2 or 3 days after taking the last pill in my pack.
This month however, I got my period last Wednesday with still 4 pills left in the pack! It wasn't just spotting, I basically got my period early (It's still going today)
Should I be concerned? Is my protection compromised? What would cause this all the sudden when I have been taking the same pill for 7 years without incident?
