Confused and frustrated

Beans

So my period is a full week late and it’s been 2 weeks since we last had sex, yet tests are negative. I must admit I am not sure about the whole ovulation cycle which doesn’t help, I read and research and end up more confused.

I have attached a pic of my tracker, I tend to ignore the blue fertility window.

The orange dot is when my period was originally due, green dot for sexual activity, blue dot for negative pregnancy tests.

I am just desperate to see a positive pregnancy result 😔
