Purpose

The primary objective is to determine if continuous COC use leads to higher continuation rates over 12 months of follow up than use of the standard 28-day COC regimen.

Arms	Assigned Interventions
Experimental: A	Drug: Oral contraceptives--ethinyl estradiol, levonorgestrel 3 visits - screening/enrollment, 6-months and 12 months

Detailed Description:

Family Health International has recently initiated a USAID funded study to investigate the pregnancy rates, continuation rates, and acceptability of COCs in women taking COCs by the 21/7 cyclic regimen compared with the continuous use of COCs with bleeding-signaled hormone-free intervals. The primary objective is to determine whether continuous COC use leads to higher 12-month continuation rates than use of the standard 28-day COC regimen. Secondary objectives are to 1) compare pregnancy probabilities through 6 and 12 months between the continuous use group and the 28-day group 2) compare COC continuation rates through 6 months between the continuous use group and the 28-day group 3) compare acceptability of the two COC regimens 4) to compare bleeding and other side effects between the continuous use group and the 28-day group 5) to compare hemoglobin/hematocrit between the continuous use group and the 28-day group
