It is reassuring that PCOS has been ruled out. Your delayed periods and weight gain may be linked to other factors like thyroid dysfunction, high prolactin levels, or insulin resistance. To regulate your cycle, your doctor might suggest cyclic progesterone (like medroxyprogesterone) or oral contraceptive pills. For weight loss, a structured plan focusing on a healthy diet and exercise is the primary step. Sometimes, generic medications like metformin are prescribed if insulin resistance is present. I highly recommend consulting your doctor to check your thyroid and hormone levels so they can create a safe, personalised treatment plan for you.
