- Can actually help transmit diseases
failure rate of 29% when used alone
Condoms
- STI protection

-Suppresses action of hypothalamus and anterior pituitary = insufficient secretion of FSH and LH - no ovulation
Maturation of endometrium altered
-Less favorable for implantation
Cervical mucus thick
-Progestin influence
Withdrawl bleeding
- occurs 1-4 days after last pill taken
- less profuse than regular period with shorter duration
- Must be examined before prescription
TAKE AT SAME TIME EACH DAY
Maintains correct hormonal levels
