What does a four days delay in period means?
It might simply mean that your period is being irregular this month. You'll know how likely that is by how regular they usually are. If you've been having sex, it probably means that you were pregnant but had a very early miscarriage. About 2/3 of fertilized eggs miscarry or fail to implant, often before you know you are pregnant. Be more careful.
Does egg implant assures pregnancy?
no pregnancies fail for many reasons. sometimes after eggs are fertilized they don't attach to the uterine wall, sometimes they do attach but develop an abnormality and the body aborts them, sometimes after the fertilized egg starts traveling down the fallopian tubes the fertilized egg prematurely attaches to the tubes and ectopic pregnancy develops (which leads to spontaneos abortions), sometimes they cant attach because of abnormalities in the uterine wall itself (like if a woman has endometriosis), sometimes trauma to the reproductive organs can cause damage to the embryo and that can cause the body to abort the child.
Why does embryo die if fail to implant itself?
