Regarding the cyst
that was discovered on your ultrasound
, it is very common for women who are ovulating to have simple ovarian cysts. These generally are produced during ovulation and usually disappear after your menstrual period. Since you have no symptoms, I would recommend that you repeat the ultrasound after next menstrual cycle whenever it does begin.
And you should also use pregnant test kit to see whether you have gotten pregnant or not. In fact, 5cm cyst is not big, you needn't do the surgery, it would bring great harm to your reproductive organs.
If you haven't gotten pregnant yet, herbal thearpy"fuyan
pill" is very suitable in your case. It could remove your cyst and eliminate all your symptoms withour reoccur.
