Opk as pregnancy test?

Sugey

Has anyone used opk as a pregnancy test? I only had one pregnancy test and it showed two lines but one very very very faint and then it disappeared. So today all I have are opk and they all say positive, I read it can detect pregnancy. I already ordered more pregnancy test, I’m waiting on amazon to deliver. I’m just anxious to know and the suspense is killing me! I am 15 days past ovulation so on the app it said to test yesterday
