I've taken 4 audition and the control row shows up everytime but nil appears surrounded by the results.
Answers: try a differnt brand but by the sounds of it if the control line shows up and result it says nil either means your not pregnant or ifits a examination where a pos or neg show up can mean trial not working .
If you are talking around a pregnancy test, get the exam that says "pregnant" or "not pregnant" in the results porthole. Should pretty much end the guessing. get a clear blue pregnancy interview they are the best and most reliable, otherwise go to your doctor..
If the control line is clear, afterwards you shouldn't be pregnant. You should still see a doctor to be sure and to rule out any other problems. Get a different brand of test. .
What kind of trial? go to the doctor and get a bloodtest
