Since you are asymptomatic, you may be managed on a conservative method. You need to have a trans vaginal sonogram and a color Doppler study to decipher what is exactly seen in your uterus
. Once it is defined, you may be needing medical assistance for further management. Try to get some help over there, or try contacting your doctor who could advice you better. If you do not have any health problems as of now, and if you are unable to get help there, you may wait with care about hygiene, avoiding intercourse and watching for symptoms like abnormal bleeding, foul smell, pain and fever
. Good luck.
