Levonorgestrel Ethinyl Estradiol Triple Photo is a second generation birth control pill, the estrogen is ethinyl estradiol and the progestin is called levonorgestrel, this birth control pill is different from other birth control pills. Normal birth control pills have the same dosage for each pill, but this birth control pill is based on the changes in estrogen and progesterone during a woman’s menstrual cycle, and the dosage is reasonably adjusted. Progesterone levels are higher after a woman ovulates, so this pill contains a higher amount of progesterone after twelve pills. The third-generation birth control pills are mainly Momoflower, Mindin Even, and Yosmin, which all have the same estrogen as the second-generation, but all have different progesterone.
