To Compare SH T00658ID Over Ortho Tri-Cyclen Lo (US/Canada)
The objective of the study is to compare the oral contraceptive (OC) SH T00658ID over Ortho
 Tri-Cyclen Lo administered for 13 cycles to healthy female volunteers between 18 and 50 years
 of age who request oral contraceptive protection. Subjects on a levonorgestrel (LNG),
 norgestimate (NGM), norethindrone or norethindrone acetate containing oral contraceptive in a
 21-day regimen suffering from hormone withdrawal-associated symptoms such as pelvic pain or
 headache or both, and willing to continue OC use but to switch to SH T00658ID or Ortho
 Tri-Cyclen Lo.
Safety issues are addressed in the Adverse Events section.
Inclusion Criteria:

 suffering from at least moderate pelvic pain, headache or both defined by an average
 of the highest 3 values of >/=35 mm on a VAS during cycle days 22-28 (35 mm VAS is the
 expected standard deviation of the population VAS reduction)

 -  Normal or clinically insignificant cervical smear not requiring further follow up (a
 cervical smear has to be taken at screening visit or a normal result has to be
 documented within the last 6 months before screening) Women with atypical squamous
