Signs of implantation could be an initial sign of pregnancy. Technically, it happens after around nine days from the date of ovulation, which is the time when a fertilized egg attaches to the uterine lining. Women can have different symptoms of implantation. Some women may not even notice these signs. That is why some women who like to detect implantation or early signs of pregnancy use an implantation calculator to be sure.
Knowing the signs of implantation is especially useful among women who are into self-defense training. Training involves some difficult moves as well as punching and kicking during sparring sessions which could endanger the life of the unborn child. If a woman is not careful enough, getting hit by punches or kicks in the stomach area or getting involved in accidents during training may terminate early pregnancy. Once implantation is detected, women who train for self-defense should exercise precautions during training.
