What to expect at 3 weeks pregnant
At three weeks pregnant your egg will be fertilized and that fertilized egg will be rapidly dividing into many cells. The fertilized eggs is making it's way from the fallopian tube, where it was fertilized and will soon arrive in the uterus where it will implant into the soft lining.
At three weeks pregnant you will probably have no idea you are even pregnant. You probably wont have any symptoms since the pregnancy hormone, hCG is not being produced yet. You might experience a little bit of spotting, know as implantation bleeding.
