I've had the symptoms that I thought were related to IBS, but a few weeks ago I was having pain so bad I couldn't hardly walk and it was off and on for over a week. I also had sharp shooting pains in my pelvic area. So I started researching and found the symptoms of ovarian cancer, I had a lot of the same symptoms including non stop lower back pain, abnormal heavy menstral flow that has led to anemia, and pressure on my bowels. I've had a lot of these symptoms for quite a while though. Ever since I had my baby who will be two soon. I even had some symptoms before I had her but nothing like now. Now they are much more consistant. But I don't necessarily have them every day, with the exception of the sharp pelvic pains which I have least once or twice nearly every day, but they come and go quickly. How long can you have these symptoms and it still be cancer? Should I be worried?
