Hello you guys I’m new to the ovulation stuff

So today I took a ovulation test the reference line was of course dark but the line that measure my LH surge is not as dark that’s negative right and also my ovulation day has past but I’m cramping my period is 9 days always and I’m done ovulating any reasons this could be ?
