Your Pregnancy This Week
You

It's been more than two weeks since the start of your last period, so it's possible (depending on when you ovulated) that you conceived this cycle. If you did conceive, a single sperm penetrated your egg within 24 hours of ovulation. This usually occurs in the upper part of the Fallopian tube. After fertilization, your egg seals itself to prevent other sperm entering. Your egg provides half of the chromosomes required to create a baby and the sperm provides the other half. It's the sperm that provides the sex chromosome (y for boy, x for girl).

Baby

At this stage your baby is a microscopic collection of cells! After fertilization the chromosomes from sperm and egg combine and create a cell that starts to divide and become a collection of cells known as a blastocyst. The blastocyst continues to multiply and grow as it moves down the Fallopian tube toward your uterus.

Symptoms

Some women experience pregnancy symptoms as early as 6 days after ovulation - so keep an eye out for symptoms. Tender breasts are the first symptom most women notice. See more early signs of pregnancy
