Whats wrong with my period?

I have had my period 3 times this month im on the pill and I usually have them at a certain time. I had my first period this month when I was suppose to and then I started again a week before my next period it lasted 4 days and stopped for a day and returned again what can be wrong with me

it might not be your period. go to your doctor ASAP. especially if your on the Pill it should almost always be regular. just check with your doctor to give you piece of mind. good luck!

Probably a hormonal imbalance, is this the first month you've been on the pill?
Go see a doctor, you may need to switch pills...
