Ethinyl estradiol / levonorgestrel
"I  only received one shot of depo. When I was due for another shot 90 days later, I didn't get it. That same month, my period never came. I read online that it can take upwards of 18-months for your period to come after depo. Over a year of no period and I wasn't alarm until my boyfriend finally prompted me to go see my doctor. She did labs and my testosterone level was elevated but the other numbers were normal.  She prescribed me Levora. I didn't take the pill at the same time every day because of my busy schedule. When I finally got on the progesterone pills in the last row, I became discouraged. On the day that I took the fourth progesterone pill, I went to the bathroom and sure enough, my period was here!! I cried tears of joy."
