What does it mean if you started your period the day before you were supposed to start your sugar pills if you usually don't start until the 4th day into the sugar pills?

Stress or illness can still wreak havock on your period even when you're on the pill. It may mean nothing. If you have taken any recent medications, especially anti-biotics, some of them cancel out the effects of the pill. A doctor or pharmacist can tell you if the medication can render the pill ineffective. Of course there is always a small chance of pregnancy, even with the pill. If it was a normal period, just early, there is probably nothing to worry about at all. If you have any other symptoms or concerns, talk to your doctor.
