Sarah, your hormones can be fine and you be anovulatory for a cycle. It simply is a fluke that happens to most women sometimes. Your body primes up to ovulate and then no egg gets mature enough to push through or your eggs were all too close so your body said uh uh not 3 or 4 eggs at once. When that happens there are two paths your body chooses. For some women they get basically a light period a week or so early as their body resets for the next try and the other option your body can take is just to start over and slowly build the chemicals again to try the ovulation again. Now, as you are so far along (60+ days) into your cycle it sounds as though your body is having trouble getting back to ovulation territory. I would suggestion taking cheap opks to see your peak again and if you don't get a positive in the next couple weeks then you may want to go to the doctor to bring on AF so your body can truly reset.
Once, before I started truly tracking, I had a 3 month cycle because it tried to ovulate twice before succeeding at cd 78. I blamed coming of HBC a couple months before and it has not repeated anything similar since.
It is very frustrating and annoying but it just happens sometimes.
