Implantation bleeding can last longer in certain situations. For instance, if a woman has a tilted uterus, it might take a bit more time for the embryo to implant properly, and this could lead to extended bleeding. Additionally, stress can play a role. High stress levels can impact the body's hormonal balance and the normal functioning of the reproductive system. So, during implantation, it could potentially cause the bleeding to be more prolonged. Also, if there are any genetic factors that affect the strength or development of the uterine lining, it might contribute to longer - than - normal implantation bleeding.
Well, implantation bleeding can be due to various things. It could be related to the embryo's implantation itself. As the embryo tries to burrow into the uterine lining, it can disrupt some small blood vessels, causing bleeding. Some women might have a pre - existing condition in their reproductive system that makes them more likely to experience longer implantation bleeding. For example, if there is some inflammation in the uterus, it can affect the implantation process and result in more prolonged bleeding.
