Hi there, I have understood your concern. I will suggest you the best possible treatment options. 1 ) First of all do not panic. 2 ) As you have the implant in place, you need not worry about the pregnancy. Even if it is bent, it still works till its expiry date. 3 ) To clear your dilemma about pregnancy , you can get morning s first sample of urine tested for pregnancy. In case of doubt blood beta HCG test and USG will be of help. 4 ) Most likely you will get negative pregnancy test results. For your irregular bleeding pattern, please seek prescription support from your treating doctor for Tranexamic acid tablets to control the bleeding. Also, it is advisable to get a gynec check up including per speculum and per vaginal examination done to rule out pelvic infection as a cause of your lower abdominal pain. I hope this answer helps you. Thanks. Dr. Purushottam Neurgaonkar.
