Period every other week

Patient: I have been taking birth control pills for the past 7 years now. About a month ago I decided to stop taking my birth control pills. My doctor has said to stop a few months before trying to have a baby. Since I got off, I have had a period every other week. They have been heavier than normal and last at least 7 days. Ive been getting bad headaches and just feel really tired. Is this normal?
