Seasonale (generic name:ethinyl estradiol and levonorgestrel) is a contraception product that contains two hormones which prevent ovulation (the release of the egg from an ovary). It is taken for 84 days (pink active tablets) and then for an additional 7 days (white inactive tablets). Withdrawal bleeding should occur in the period when the inactive white pills are taken. If spotting or breakthrough bleeding occurs, the patient is instructed to continue on the same regimen. This type of bleeding may be transient and without significance; however, if the bleeding is persistent or prolonged, the patient is advised to consult her healthcare provider.


Given the information you provided (heavy bleeding lasting for hours and getting worse after intercourse), you might be experiencing a hormonal imbalance which might be a side effect from using Seasonale. You are advised to visit your gynecologist for a physical examination and hormone laboratory tests to check if the condition is caused by the Seasonale and if other birth control product might be better for you.
