Ovulation test detecting a pregnancy ???

Shika

I’m posting this on the behalf of my cousin. She is 4 days after her missed period. She took a pregnancy test and it was negative. So, I suggested that she try a ovulation test and it came back with a dark color line but not as dark as the control line. I felt that she maybe pregnant because how the ovulation test came out…any advice cause she is driving herself crazy not knowing what’s going on with her period. Do she supposed to see a positive pregnancy test by now? This is her ovulation test
