Weeks 0 – 4
Wednesday, September 15th, 2010Babies
Your babies are developing quite rapidly. By the end of the fourth week the ball of cells (blastocyst) begins to tranform into an embryo. During this time, the baby’s brain, bladder, liver, kidneys, spine, extremities, reproductive tracts and heart are all beginning to develop.

Pregnancies are dated from the date of your last period, so for the first two weeks you are not actually pregnant. Your babies will be conceived by the end of the second week. You will not know that you are pregnant yet despite there being a lot going on inside your body, however you may experience a few pregnancy symptoms similar to premenstrual ones such as breast tenderness or nausea. An over-the-counter pregnancy test may give a positive result by week 4 and a blood test would almost certainly give you an accurate result at this stage.
