4 days late and now odd bleeding, please help

So 4 days late and started bleeding...

It started off as

10:00am: Brown/black then dark red also with clearly egg white discharge

5:00pm it’s now brown with little spots or so of red blood...

None of this is heavy

I thought I’d be having faint pregnancy tests but now I’m confused on what could be happening 😫😫😫 I’m confused on what’s actually happening!! Does anyone have any advise?? Xx
