Cycle day 58, no period, and starting provera

Well this is the longest I've gone without a period. First day of my last was 9/5/15 I had a blood test on cycle day 53 that came back negative so I started provera today. This is the longest I've gone without a period and with having a negative test it's like all this time without it for possibly nithing. My longest cycle I have had before was 45 days. Has anyone ever had something like this happen? It's bothering me and I have no one to talk to that understands what I'm going through. Their just like that's crazy you haven't had it yet. I just wish my body could be normal.
