Sixty two percent of women between the ages of 15 and 44 use some form of birth control, whether that’s a pill, or something like an intrauterine device (IUD). That’s according to Dr. Laurie Birkholz, a women’s health physician at Lakeshore Health Partners. Not only is contraception a way to prevent unwanted pregnancy, it helps women plan when they want to have a child. It can even help with things like acne and heavy bleeding. While contraceptives are meant to prevent pregnancy while in use, some say they’re flat out causing infertility.
