Wishn, I totally would do it today. They will probably give you an ultrasound and the doc can tell you where you are in your cycle when they do that too. I totally would! But I'm a big nerd that wants to find out everything about my body. When I was 8 my parents walked in on me reading the medical encyclopedia and asked me what I was doing. My reply was, "I'm not feeling good so I decided to find out what's wrong with me." In a total serious face no less.
Good luck at your appointment! What were the symptoms of a cyst that led you to go in? I've had one ovary that seems to hurt all cycle except during my period, but it's been going on a few months now. They say most cysts resolve on their own so I didn't worry about it, but have my regular "womanly" exam on 12/7 so I figured I could ask about it then if it was still bothering me.
