Confusing moment

Carlessa

Okay so I have irregular AF and I’m 4 days late and signs of AF showing up. But i had notice when wipe i have streaks of brown discharge and when I check my cervix it was a little bit of blood and discharge. I took a pregnancy test the first day I missed AF and I took another one yesterday and it came back bfn. Idk what’s going on have anyone experience this. We are ttc. Am I testing to soon? And wait till I’m a week late 🤷🏼‍♀️
