HI There,
yes , that can happen. Bleeding into a cyst of ovulation can sometimes look very dramatic . It can also look like endometriosis.
Now that the report has come back showing no sign of endometriosis or cancer, it would be safe to start a low dose estrogen replacement. Reports (The Women's Health Initiative (WHI)) suggest this is safe to do into your sixties.
best wishes
The pathology report says:
-Portions of hemorrhagic corpus luteal cyst(s) wall
-H&E sections demonstrate portions of luteinizing follicular cyst wall with areas of organizing hemorrhage
-Suggest clinical correlation
