What it is

October 24, 2019

Lo/Ovral-28 contains a combination of ethinyl estradiol and norgestrel. Ethinyl estradiol and norgestrel are female hormones that prevent ovulation (the release of an egg from an ovary). Lo/Ovral-28 also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
