 One in 10 women who still get, so not all women get pregnant when they take OPIL, but a high number still do. When women get pregnant while taking OPIL, one out of 10 of them who do get pregnant while on OPIL have a life-threatening ectopic pregnancy. Why is that frightening? Because women think that when they're on birth control, they're engaging in, quote, safe sex. So they're less likely to test for potential pregnancy because they don't think it's a possibility.
