The embryo should pass over the body defense system and engrave the inside of the uterus with the help of some secretions it produces and nested here to be able to implant on the mother’s uterus. Through the secretions (enzymes and factors) it produces, it destroys a number of intrauterine cells, then it moves towards this space by producing its own cells. It again destroys a portion of cells and continues to move by producing its own cells. The embryo proceeding in this way first embeds itself deeply in the intrauterine tissue, and then grows back into the uterus. After filling the intrauterine space, it starts to enlarge the uterus.
During this dissemination, the embryos sometimes run into the vessels feeding the uterus. If you want to proceed by creating a space as always they do, bleeding occurs due to the damaged vessel. This bleeding is often discharged from the cervix and is noticed by the patient. In some cases, it is trapped in the uterus and is noticed only when ultrasonography is performed.
Since there is no test to differentiate whether this type of bleeding is an implantation bleeding or a miscarriage threat, the bad assumption is put forward in any case. In other words, each bleeding is considered as a miscarriage threat and the patient is kept on absolute bed rest. Some drugs are initiated to help keep the baby in its place. After spotting recovers, the patient returns to her daily routine.
