4 days late and negative tests..

I’m 4 days late. I don’t even feel like I’m going to start my period. I usually get cramps a few days before. I took this test this morning and it’s negative. I know I ovulate late every month, is there still a chance I could be pregnant?

I took this on Sunday and swear I could see a faint line, but now nothing since.

I’m so confused 😞

Could it take longer to get a positive test if I ovulated late??

It’s so frustrating, I want to be pregnant so bad, but if I’m not I just want to start my period so I can continue my tests at the fertility specialist.

Thoughts??
