How long does it take for a blastocyst to implant?

about 7 to 8 daysIn the case of in vitro fertilization (IVF), the fertilized eggs or human blastocysts normally hatch out of their shell and start to implant about 1 or 2 days after the 5th day of the IVF blastocyst transfer. This means the implantation takes place about 7 to 8 days after fertilization of the egg.

What are the signs of implantation failure?

The IVF implantation failure symptoms are quite evident by the absence of any changes. Implantation generally causes changes in the tendency to smell, increased sensitivity of breasts, vaginal discharge, and slight abdominal cramping.

Can stress cause an embryo not to implant?

Stress can prevent the implantation of a fertilized egg. Stress can affect hormones that reduce blood flow to the uterus and endometrial lining making it less receptive to implantation.
