My mother died of ovarian cancer when I was ten congrats for passing it up, your in my prayers for your chance last year. Im amazed they were able to save your other ovary considering the size of a football tumor would put you almost at risk of getting it again. Let alone I would of thought it would have been touching the other ovary...My prayers are with you, as for the others who think you may have cancer, its a simple check with your gyn, if your worried and concerned and in pain and freaking out, go have labs run, get an u/s done, get a ca-125 done, there are things to be done to reassure you that you do not have cancer, and more than likely like me have pcos or endo and your periods are just wacked out and running on estrogen timing or progestrogen and wacked out hormones and ovarian cysts that need to go away!! Lol...We all stress out during our cycles which will trhough our bodies out of wack, we over eat sleep and exercise or under do those things wich in turn throws our bodies out of wack as well....So please check with your doctors and tell them whats been happening and check into your family history and record your menstral cycles and let them know about your problems, and yes talk to your parents about the possiblity of birth control for the sheer fact that it could potientaly help your hormones and decrease the risk of of harmful diseases!
