Help😩😩

I’m on CD 36 with zero period symptoms. My cycle normally lasts 30-33 days, I took a test tonight after not peeing for around 5-6 hours and it was negative 😩 I ovulated around March 22-24. I also had my first chemical last month, so that might be throwing it off. Any advice?? Do you think I’m out 😔 I just wish I knew what was going on with my body.
