First time using ovulation strips

Hello guys, I’m sure you guys get annoyed with these all the time lol but it’s my first time using them ... according to <a href="">Eve</a> my fertile days begin in 3 days ... the strips came in the mail yesterday so I took one today just to test and it looks positive if not almost there ... can someone help confirm if this is actually positive 3 days before <a href="">eve</a> predicted? We been trying for a few months based on eves predictions and been unsuccessful so maybe it’s because I O’d earlier ?
