Dear user, welcome to healthcare magic.
The urine test is not sensitive enough. If you want to be sure you should have a blood test
. This is more sensitive and reliable.
What is more important for you is that you should have someone who is grown up enough and reliable so that you can tell him your problems. One who can give you an honest advice and help you out this problem. Please do not take decisions for yourself. You are too young for this.
Dr. Ahmed Bahaa.
