How many days after fertilization does the fertilized egg become a blastocyst? Then embryo? What implants-the blastocyst or embryo?

How many days after fertilization does the fertilized egg become a blastocyst? Then embryo? What implants-the blastocyst or embryo?

The process: As the fertilized egg divides, it is first known as a morula. Approximately 5 days from first fertilization it forms into a hollow ball known as a blastocyst. This blastocyst implants and begins to sort itself out into different layers--the inner group becomes the embryo and the outer layer will work to nourish and protect. At approximately 6-7 weeks from time of fertilization, an embryo begins. ...Read more

6w 4d pregnant with fetal pole, yolk sac ...heartbeat detectd...but seems gestational sac is irregular...sign of miscarriage?

Don't worry: The most important thing is that the fetus has a heartbeat. Did they tell you an actual fetal heart rate? Sometimes the gestational sac looks different. There could be a nearby fibroid or subchorionic hemorrhage. Signs of a miscarriage are uterine cramping and bleeding. If you are not having those symptoms I would not worry about this. The sonogram can be repeated in 1-2 weeks. ...Read more
