Its a common problem faced in PCOS and is due to hormonal imbalance which can be due to multiple reasons like:-
As you said office tension/ stress not good
Thyroid problem (when was the time you had
TSH done).
Overweight
Consult you gynecologist, discuss with her and you should consider OCPs to improve hormonal imbalance ( if not planning to convince in case you are married). Try to remove stress as much as possible
