irregular periods - advice please

Stacy
Hello,
I've been off the pill for 11 months but periods returning only 7 months ago. But my periods are inconsistent, either late a few days or early a few days and never last the same number of days.
This month (today) I've started my period a week early. I've also gained 1stone since coming off the pill.
Should I see a doctor about this? Or is plus or minus a week fine?
Thanks very much
