More movement, wrong direction

It's been a while again since I've last posted.  That's good!  At the end of 2013 CA125 was 12 so we went back to checkups every 6 months.  It seemed like a long time, but honestly I didn't think about cancer too much at all.  Last week the blood test on May 2nd showed the numbers up to 35, we retested on May 7th, up a bit more to 41.  The plan is to retest again in 4 weeks.  My onc is still saying he doesn't think it's ovarian cancer, but it's hard to not worry...
