White line? Desperate!

Sarah

I've been taking pregnancy tests (strips) since 12dpo and now it's CD 28. I'm on the week off my BC and I took plan b when I had sex which was about a 2 weeks and a half ago. I've been feeling very nauseous, pee a lot, lost my appetite, have cramps, acne, bad headaches... It's a mix of side effects, PMS, and pregnancy. I've read many women experience nausea and headache because of the ring or their period is coming. Today I took at test with FMU as I've been doing for almost a week now and when I was using my light to see better there was not one, but two white lines. No type of dye there, just two white lines before where the default one has to be. I'm confused since yesterday I felt like my period was here. I felt wet and my dog was smelling my ass just as when I'm on my period. My partner didn't even cum inside so I don't know if for some weird reason I'm pregnant on the ring, plan b, and precum. I can still wait for later today. But should I buy other tests? Like I said the rest have been all negative without weird lines. Here you probably can't see the line but I'm just losing it.
