Overall MOA: STOP OVULATION
Progestin inhibits the LH surge, thickens cervical mucus, and inhibits ciliary activity in oviducts
Estrogen inhibits FSH, and improves endometrial stability -> less bleeding

Your patient wants to get on contraception but doesn’t like the idea of delayed return to fertility. What should be avoided? What is a good option?
Depo Provera should be avoided
