Rather than waiting for weeks to find out whether you are pregnant, learn about some of the early signs of pregnancy. As early as the first two weeks after conception, your body may produce symptoms associated with pregnancy. Knowing what to look for and expect may help you realise your pregnancy earlier, even before taking a pregnancy test.
First Two Weeks Pre-conception
Pregnancy is calculated from the first day of the woman's last period, so the first two weeks of pregnancy are actually the preconception weeks. During this time, the woman is probably not pregnant yet. During the 10 to 14 days following the first day of the woman's menstrual cycle, she will release an egg that goes down her Fallopian tube. The egg then waits to be fertilised by the father's sperm. On average, women have a 20 per cent chance of becoming pregnant during each cycle. Some women experience no symptoms at all, however, so if you don't experience any symptoms in this time period, it doesn't necessarily mean you're not pregnant.
First Two Weeks Post-conception
Once a sperm has fertilised the egg, the woman is pregnant. She will probably miss her next period. During the next two weeks, she may also begin to experience some or all of the following symptoms (remember that a lack of symptoms is normal, too): tiredness, nausea, breasts that become tender, a metallic taste in the mouth, the need to urinate more often, temperature that remains high after ovulation (normally it will fall), headaches, backaches, mood swings, slight bleeding or cramping (when the egg attaches to the uterine wall), constipation and disturbances during sleep. Most of these signs of early pregnancy will appear toward the end of the second week after conception, but occasionally a woman will notice them slightly earlier.
Baby's Development During First Two Weeks Post-conception
During the first few weeks, the gender of the baby is determined. The egg that has been fertilised is called a zygote, and it begins to divide. As its cells multiply, the zygote burrows into the uterine lining. The future baby is now called a blastocyst, which is a ball of cells. The inner area of cells will become the embryo, and the amniotic sac will form from a cavity in the blastocyst. The placenta will eventually form from the outer cell body.
