I took loestrin 3 years and loved it. Short periods. For the past year I couldn't afford it so stayed abstinent for the most part. The day after my last period I restarted loestrin, everything was great until I had sex a week later and I've been bleeding old blood like a normal period ever since (~week) and have horrible cramping and ya know, the runs... I've been online reading horror stories saying this will last for months. Please, some advice?
