No, this is incorrect.

> The birth control pill works by stopping sperm from joining with an egg. When sperm joins with an egg it’s called fertilization.

> The hormones in the pill safely stop ovulation. No ovulation means there’s no egg for sperm to fertilize, so pregnancy can’t happen.

> The pill’s hormones also thicken the mucus on the cervix. This thicker cervical mucus blocks sperm so it can’t swim to an egg — kind of like a sticky security guard.

This is correct with the additional caveat that the pill also thins the uterine lining, making it difficult for the embryo to implant in the rare event of fertilization. So for people concerned about avoiding an abortion, the pill rarely, but not never, results in abortion.

Or as my partner says: my tummy is making a baby nest, but it’s always empty.

I vaguely remember misinformation about birth control in Catholic school. They told us that IUDs kill fertilized eggs.

It was completely wrong.
