When should I test during the day for ovulation

Traci

Please help. I havea 41 day cycle I've been testing twice a day around 11am and 7pm. All negative since February 12th when I got off my period i also hold in my pee before testing and I don't drink to much water before testing. Can anyone tell me what I'm doing wrong ? 🙃 also my period is suppose to start around the 7th this month.
