The fetal stage don't start until week 10 so by now it's a blastocyst. Implantation begins about 6 days after fertilization and is complete by about 12 days.
Yes, you should be concerned. It is quite possible you are experiencing symptoms of an ectopic pregnancy. This is when the fetus attaches itself to the inner wall of one of the fallopian tubes. It will not show up on a pregnancy test. Please seek immediate medical attention with an OB/GYN doctor. The growing fetus will cause a rupture of the fallopian tube. If caught early the fetus can be removed without permanent damage to your fallopian tube.

The cervix (opening) is closed and the uterus filled with liquid the fetus float around in. It's attached with the umbilical cord to the placenta which is attached to the uterus wall. The uterus expands as the pregnancy progress.

Oftentimes, an egg is fertilized during ovulation but doesn't "take." Instead, it's shed with the uterine lining when your period comes. A pregnancy, however, means that the fertilized egg does indeed "take." It attaches to the uterine wall and the amniotic sac begins to develop to nurture the fetus.
