Hi, Welcome to HCM
First of all mention your age. The lesion mentioned in fundus possiblly looks like a small fibroid
In worst case scenario the fibroid may cause excessive bleeding during menses and second trimester abortion(if in the range of parity age), but this lesion is too small , so dont worry too much.
second thing,please tell the lesions in both adenexa are seen separately from ovary or not. Then only it will possible to tell whether they are normal or any pathology. Endometrium is not thickened so no risk of endometrial(uterine) cancer.
