This is definately something that your doctor should have more definate information on. If they suspect something like endometriosis then they should be testing you for those things. A lot of your symptoms are normal for most women and are pertaining to hormone fluctuations. It is possible that you do not have ovarian cancer, but maybe a hormonal imbalance. In fact, there are also many other things that are less extreme that cause those symptoms. I recommend either getting more from your doctor or a second opinion!
