This is one of the reasons that women need to pay attention to what is going on with their bodies and to speak up if there is something different happening and they are worried about it. It sounds like ovarian cyst symptoms could be mistaken for a heavy period or something similar and I've had occasions where I've gone to the doctor and told them that I've been in pain and that my period is too heavy and they've essentially told me that it's just a woman's lot in life and that I shouldn't be so over dramatic.
It turned out that I have endometriosis, rather than cysts, but it took a long time to find a doctor who would take that seriously. And if a woman is bleeding from an internal injury, they really need help right away.
So make sure you have someone there who won't take no for an answer, even if you have to be that someone yourself.
