What is implantation bleeding mean?
Implantation occurs normally around the time when you’d be expecting your period. This early stage of pregnancy can cause cramping and some spotting, but many moms-to-be feel no change (yet!) in their bodies. During week four of your pregnancy (about five days after conception), implantation occurs. Once the embryo, now called a blastocyst, reaches the uterus, it searches for a nice place to implant. Then it burrows beneath the surface of the uterus and its cells begin to divide into two groups: those that form the placenta and those that form the baby. it should not be like your regular period.
