Early pregnancy symptoms: 3 weeks
At three weeks pregnant you will not even know you are pregnant yet. During the third week a lot if going on inside of you. The fertilized egg is busy traveling down the fallopian tube and implanting into the uterus. Some women might experience spotting or cramping during implantation. It is normal not to experience any symptoms though, so don't worry if you don't have any. As soon as the fertilized egg implants into the uterus your body will start producing the pregnancy hormone hCG. Once the hCG levels start building up in your body you may start to experience the classic pregnancy symptoms.
