PCOS is confusing and stressful - Advice please?

I’m now 14 months postpartum, still breastfeeding and had irregular cycles since maybe January. I have had one completely missed period in April that was unexplained. I had three pregnancy test taken that month and all were negative.

So it looks like I’m having another missed period ...

I felt a cyst form a few days after ovulation and it popped a week later so I am blaming that for Aunt Flo being missing.

Yes there is a chance I’m pregnant- however I have zero symptoms.

I have had two weeks of very light cramping which I normally get around my period.

I just want to know if this is normal with PCOS after a baby? I don’t normally miss periods.
