Am I out or not?

I honestly don’t remember how many dpo I got positive tests with my other babies so please help me. I have zero idea when I ovulated. Anywhere between the 23rd and 30. I took a test today and it was negative. My period is supposed to come July 10-12 but I just got off Mirena so it’s a little whacky still. Should I assume the negative was correct or wait a little longer to make sure before I test again? I used a cheapie Walmart test and I thought those were supposed to be super sensitive so I thought I was out for sure.
