Hi and thank you so much for this query. The truth is that, when you miss your demo injection, the chances of getting pregnant are real. What I don't understand is why the pregnancy tests are not giving the same results for your sister when she uses the one that you used. Did you check the dates and make sure the tests were still good for use? Hope so. My advice is that you get a different brand of pregnancy test and repeat the test with. If the results are consistently negative, then you are most likely not pregnant. If the test should turn out positive, the visit the hospital and get this results checked out. I am so sorry about the inconveniences this has caused you. Please, always take your prescriptions serious to avoid future situations like this. Also, also consider using protection when having sex to help prevent STDs in addition to unwanted/unplanned pregnancy. I hope this ad Chat Doctor.  Feel free to as me more questions if need be. Thank you so much for this opportunity. Wish you the best of health.
