baby : congratulations! if your egg and your partner's sperm have joined successfully your embryo is really there although it's very small -- about the size of the head of a pin. it doesn't look like a fetus or baby; it's just a group of about 100 cells multiplying and growing rapidly. the outer layer of cells will become the placenta and the inner layer will become the embryo. mom-to-be : you won't notice any changes. it's too soon. remember you haven't even missed your period yet. tip for the week : home pregnancy tests are about as reliable as a urine test or blood test done in the doctor's office and can give you more immediate results than waiting for a doctor's visit. to ensure accuracy make sure you've read the directions carefully and that all equipment being used is clean.
