Hi. Thanks for asking in Healthcare Magic. Although highly effective, Depot progesterone is not suitable for young girls like you as it can either cause irregular bleeding, excessive bleeding or absence of regular periods. These complications increase when you use it frequently as your case may be. Depot progesterone is indicated only for those who are most unlikely to use other contraceptives effectively. It appears that your cycles are disrupted. If the bleeding pattern continues to be irregular, you should consult a gynecologist for necessary guidance. Drugs like Tranexamic acid may be helpful but check with your Dr before you start any medication as it can be taken only after your Dr s advice. I hope this is useful to you.
