Also known as: Miscarriage, Lost pregnancy
A miscarriage is the loss of a pregnancy during the first 20 weeks. It is usually your body's way of ending a pregnancy that has had a bad start. The loss of a pregnancy can be very hard to accept. You may wonder why it happened or blame yourself. But a miscarriage is no one’s fault, and you can't prevent it.

Miscarriages are very common. For women who already know they are pregnant, about 1 out of 6 have a miscarriage.1 It is also common for a woman to have a miscarriage before she even knows that she is pregnant.
