You may be suffering from either a recurrence of your previously diagnosed
MajorMajor tears
Major-gesic Depression or
PMSPremenstrual syndrome
Relieving pms or currently known as PMDD or PreMenstrual Dysphoric Disorder.
Both disorders may be treated with antidepressants belonging to the Selective Serotonin Reuptake Inhibitor (SSRI) like Prozac or Zoloft.
The latest information from published literature indicate that you may take the SSRI only during the luteal phase of your menstrual cycle. The luteal phase is the period of time(usually 11-14 days) following ovulation. This is provided you have a regular 28 day cycle. If not, this strategy is not recommended.
The SSRI's are relatively safe medication and have minimal or low interactions with other drugs, however, I would suggest informing your doctor that you are taking oral contraceptives before starting any antidepressants.
I suggest a consult with a Psychiatrist for an evaluation.
