Am I pregnant TMI POST

So I took 2 test this morning both with faint lines that you can see with eyes but not on camera, 20 minutes later start with light bleeding brown and light red. Took another (diluted wee) camenback negative. I've put a sanitary towel on 2 hours ago checked it, not enough blood to change but enough to question if period or chemical. I'm also having to pee alot too.
