I know this is a weird question but

I read somewhere that an opk can sometimes determine pregnancy. So to avoid wasting my good FRER I decided to pee on an opk with not my FMU and got the FAINTEST line. I’ve never gotten two lines on an opk EVER. Tomorrow will be 3 days late for me can you guys tell me if I’m crazy or if I see the line. I know it doesn’t mean I’m pregnant I just need confirmation that my line eyes aren’t so bad that I’m imagining things!
