It is possible. I have gone through this. If the test is below the 90% accurate test it could be a fake positive. You really need to go to your local health department to find out for sure. I know your scared, but you need to do this.
Okay go to a clinic make sure the test is accurate and when results. Are given then decide to seek ur partner and let him know two heads is better than one when one is scared support from friends and family can help too
