How did you find out you had pcos?

I’m currently 18 days late went today for an appointment took a urine test I did not have much to pee bc I was told to take a test before I came in, test was negative Its not unusual for my period to be late but for it to be 18 days it’s unusual so once she told me my test was negative I was like I didn’t have much urine can we take a blood test ? Bc I’ve heard some women have negative urine but positive blood test, I was told it was unnecessary that it’s okay to skip a period that if I wanted to get check for cyst bc I’m having right side ovary pain an some left side as well as some breast pain. I did a pap everything came back neg I was told by my doctor in Texas I’m clean no cyst or anything I’ve recently moved to mn an the appointment she wants to do a vaginal ultrasound an she’s concerned if I have cancer, but my obgyn in Texas have me a clear last month. I’m so confused what should I do!
