Hi, I Am 32 Years Old. My Periods Started At

Hi, I am 32 years old. My periods started at 14 and stopped when I was 16. I consulted doctors and it was a case of premature ovarian failure. Now suddenly at 31 years, I started having regular periods again. However this month, the periods happened after a gap of 2 months and is basically spotting rather than normal flow. Please advise.
