Missing Periods?

ma

I was on the pill for 6 years and got off of it in Oct. I had regular periods the first 2 months after getting off of the pill. Since then my cycle has gotten longer each month, last cycle was 44 days long. My dr says there’s a chance I have either Endometriosis or PCOS that could be causing it (she also found follicles on one of my ovaries and noted they could develop into PCOS). Now I’m on day 65 of my cycle and no period. Not pregnant, just late. At this point I just guess I didn’t ovulate and I won’t have a period this cycle. I have had a teeny bit of spotting the past few days. Does anyone else miss periods? Does this mean I don’t have a “cycle”? If I don’t have a period for a few more months should I be worried? Any natural remedies to regulate my cycle?
