Bleeding during pregnancy

Has anyone else bled through all of your pregnancies or just for some of them? I just found out from my mother that she bled through out her whole pregnancy with my baby sister. She was the last baby. I’m wondering if this is something that’s genetic at this point? Maybe every woman in our family just has a more easily irritated cervix?? I wonder if any of you experienced having no bleeding whatsoever and if you did have bleeding and how was your pregnancies??
