More tired than usual

I think I'm about 9 days late. On day 43 of my cycle. Last month was 30. I was bloated pretty good a few days ago and had some cramps so I thought I was going to start so I put I tampon in. Took it out the next morning and there was like a spot of light brown discharge/blood. Bloating was gone. Haven't bleed since. And I've also been more tired than usual. My schedule hasn't changed. Nothing has changed for my cycle to change. Got a bfn like four days ago. My boobs are a little tender that's it. Going to test again tmw.
