Hi. Well, don´t be scare about it, as I understans you have symptoms of abdminal disconfort and pelvic pain, remember that there are alot of things that can upset the pelvic area like urinary infections, colon problems, and ofcourse we have to think about internal genital organs like ovaries and uteru. Ovarian cancer as I understand can be curable just if it is detected early as it does with breast cancer and cervical cancer by means of mastography and pap. So it will be prudent tu look for a ultrasound.....it says that if you have 3 months with constipation abdominal upset, menstrual irregularities, pain it will be o.k. to check this. but not just the ultrasound. it will be best to be examine physicaly by a doctor too. so he can analize everything. if the ultrasound has a tumor the next step is a ca 125...but there are about 4 serological tests not just the ca 125. so it will be best.. to see a doctor. to find out what will be the best for you.. and don´t be worry ..there are alot of other things that can be easly cure and not just cancer. be brave!!!!
You need a sonogram to see if there are any cysts/masses on your ovaries before you should even think that you might have OvCa.
The symptoms could be various things, even IBS. Remember will not show anything at all with your ovaries or uterus for that matter. It is just a test for cervical cancer.
You can always go to the ER and tell them your complaints, they might do a CT Scan right then and see if there are any issues on your ovaries.
Hang in there.
