Hello ma'am and welcome.
There are various factors missing in your query like youe sexual status, history of medications, birth control, age, etc. Which is why it would be difficult to comment on the possible causes.
But the fact that you have been diagnosed with PCOS
would be the most likely explanation for your presentation right now. Please meet youe doctor for a more elaborate evaluation, diagnosis and treatment accordingly. For now it is clear that you might have a hormonal
imbalance and so we need to find the cause.
Hope this helps
