l used 7 Biosure test kits at 6,7, and 8 weeks after possible exposure and after 20 minutes to 2 hours the result were negative thus there was only one visible line surprisingly hours later a faint pink/purple line would show on all the test kits. l am really worried.
Our test has a 12 week window period, you can of course test at anytime during this period but it will only give an indication of your result. Testing 7 times during this period is unnecessary and may only be worrying you more. I would recommend to wait until you are past the 12 weeks to test again. Secondly, you should never read your result 15 mins before or 1 hour after performing your test as your result may change. If there was only the single control line visible between 15 mins -1 hour then your result is negative. Just remember to retest at 12 weeks for a conclusive result.
