Irregular periods. I have a cyst again?

Hii... irregular menstrual cycle is quiet common in PCOS. Weight gain,hair fall and acne are typical features of PCOS. There is no permanent treatment for PCOS as it is not a disease but it's a cluster of some features due to hormonal disturbances. Lifestyle modification is the best option for controlling severity. It includes diet restriction to 1200cal- for this u can do calorie counting by installing any  app (eg,healthify me), and doing exercises like brisk walking/skipping(diet +exercise works better,than either alone- so no cheating) . Atleast 5% -10% of weight loss will correct hormonal changes and regularise ur cycles. If you had sex then it's always better to rule out pregnancy first. So better u consult a doctor nearby who will evaluate you in detail and prescribe you accordingly.

Undergo urine pregnancy test first. Then u can consult a gynaecologist who will do a basal scan and give medicines for withdrawal periods and suggest you on haemorrhagic cyst depending on its size.

limit rice and rice products - as they are carbohydrates and u will gain weight quickly. Take plenty of fruits and vegetables. U can replace rice with either quinoa or millets.
