Anovulation after miscarriage

Jessica
Last month I had a natural miscarriage at 5 weeks. It was my first pregnancy after 17 months of trying. After I stopped bleeding I ovulated again (checked with tests and temperature) and then AF came. I was relieved that my body was finally back to normal and we could start trying again, but then there wasn't ovulation! I had the positive ovulation tests and fertil MC, but no rise in the temps. This hasn't happened to me before. Have anyone experienced anovulation after a miscarriage? How many cycles until back to normal?
