3. Theroretical/proven risks outweigh benifits, not reccomended unless more appropriate methods are not available/acceptable
4. Unacceptable health risks
Actions of Progestin and Estrogen
Progestin
* ovarian and pituitary inhibition
* thickening of cervical mucus
* endometrial atrophy/transformation (thins lining)
* Cycle control
Estrogen
* ovary and pituitary inhibition
* thinning of/increase in cervical mucous

* cycle control - allows for period
Exams and tests prior to initiation of birth control
- LNG and Cu IUD: bimanual exam
- COC: Blood pressure
- Diaphram or cervical cap: bimanual exam
- if sexually active offer STI test via urine if no pelvic exam
- unnecessary tests can be a barrier to starting effective contraceptive
