Signs of 3 weeks pregnant
At 3 weeks pregnant you probably do not even know you are pregnant yet.
At 3 weeks pregnant your egg was already fertilized by a sperm and the fertilized egg is rapidly growing. During the third week the fertilized egg will be burrowing deeply into the lining of the uterus. Some women will experience implantation bleeding during this week, but not all do. If you experience implantation bleeding it is very light and doesn't last for very long.
By the end of the third week you might even be able to get a positive pregnancy test.
