<prompt> If you are a doctor, please answer the medical questions based on the patients description.HI, I have been on implanon for over a year, no period for 7 months. I have had negative urine pregnancy tests, cravings, nausea, mild pelvic cramps, jaw pain and gained about 4kgs. Today I felt fluttering in my stomach, and I m confused because I know you can have pregnancy symptoms as part of the side effects.  <response>: Hi there, I have understood your concern. I will suggest you the best possible treatment options. 1 First do not panic. 2 As you have missed your periods and your home pregnancy tests are negative, then please get blood beta Chat Doctor test to confirm or rule out the pregnancy. 3 If you have negative pregnancy test results, you need not worry about the pregnancy. Implant can cause all these symptoms per se too. It is not a reliable sign of pregnancy.4If you are still worried, get a pelvic ultrasound done too. I hope this answer helps you. Thanks.
