Dr. Hanif warmly Welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns.   Reason is hormonal imbalance. When you are off birth control treatment, it causes the body to readjust itself according to matural way and to the previous normal.levels. But the process takes time to kick in and to make the hormonal levels normal to the limits. This is normal but takes some time. You will take a couple of months to come back to normal periods as you had before starting birth control. Hope I answered all of your health concerns . If you have further questions in future, feel free to contact me anytime. In the start of your question write my name, and I will get back to you in no time. If satisfied, please click you found it helpful. Have a wonderful time ahead.   Best Regards! DR. MUHAMMAD M. HANIF USA
