Hello, Thanks for posting your query. There could be many reasons for delayed periods other than pregnancy, like stress, anxiety, hormonal imbalance, illness etc. Regarding your symptoms of heavy flow followed by brown discharge this can occur in times of stress or if you are anemic or ill. You can take some iron supplements like Fefol Z capsules one daily for three months and add plenty of green vegetables and milk in your diet. If your period is delayed by more than a week then you can get tested using a home pregnancy kit. In case your pregnancy test is positive and you choose to go for an abortion, please consult your gynecologist who will guide you. This is important as any self methods could be potentially harmful to your health. If you continue to have delayed heavy flow every month, Please consult your gynecologist who will examine you and give the appropriate hormonal treatment to regularize your flow. Hope I’ve answered your query. Regards,
