OPK help

So probably a week after my period I took a opk for the first time ever and got a faint line which I’ve read is negative. The next day I took another and the line was even more faint and today I just took one and there’s no line at all? Did I miss my ovulation? I’m in my fertile week now according to glow with ovulation in 3 days . Also had s chemical last cycle. Would it be that negative if I was going to ovulate in 3 days ?

First one taken

Take the next day

Taken today
