So confused

So it’s been 2 years since my youngest was born yet I feel rusty on EVERYTHING related to ttc 🤦🏻‍♀️

Here’s my calendar from the past month. You can see ovulation on the top and predicted period on the bottom never came. I’ve taken test a couple days before my supposed period, the day of my supposed period, and a couple days after I took two more tests. One was even a digital.

All have said not pregnant / negative

This past week I’ve had intermittent light cramping and gas. Signs of period with no period. I’ve also been grumpy, no patience, and tired/unmotivated for days.

Any one else not gotten a positive for more than a week after a positive should of been picked up on a test?

Anybody have any other ideas as to what could be happening here?
