The fertilized egg has reached the uterus and embedded itself in the uterine lining. It’s now known as a blastocyst. When the fertilized egg embeds itself in the uterine lining, light bleeding known as implantation bleeding may occur. If this happens, it will be about one week before your period is due. Implantation bleeding is harmless.

The placenta begins to form around the embryo at this time. The embryo receives all its nutrients from the yolk sac.

The embryo is minuscule at this early stage of the pregnancy, and most women have no symptoms. That said, some women may already be experiencing nausea, tender breasts or very sensitive nipples.

Your body is now producing human chorionic gonadotropin, a pregnancy hormone that is excreted in your urine. A simple pregnancy test will reveal whether you’re pregnant as early as weeks 3 to 5.

This first part of your pregnancy, up to and including week 12, is known as the first trimester.

The embryo is now growing in the womb and all the organs are starting to form. You may have done the pregnancy test and know a baby is on the way, or you may not know yet.

Finding out you’re going to be a parent is a life-changing experience, of course, but a negative pregnancy test can be tough for couples who have been trying for a baby for some time. Talk with each other about your thoughts and feelings—your happiness and sadness, your excitement and anxiety.
