[/INST] Dear FriendWelcome to Chat Doctor I read your concern and would suggest that taking pills without knowing cause for irregular periods is not advisable. Therefore, I would say you to get checked for health problems like thyroid disorder (Hypothyroid can cause irregular periods) Low hemoglobin, PCs .Therefore, consult a gynecologist and speak to her about your problems. My advice is to stop pills as weight gain is risk factor for further Irregular periods not be stressed., Keep mind relaxed by relaxation techniques. You can ask me further if you have any doubtsRegards Chat Doctor. Kingston John David </s>
