Who else has had AF but actually implantation? Pls read

[angel4eva]

I started what I thought would be my AF Thursday, and normally it lasts 7/8 days, but by yesterday it was really slowing down and now there's hardly anything and it's brown on day 4

I'm feeling really nauseas, emotional and really irritated by everyone and everything!

I did a test this morning, but it was a bfn.

I'm so confused and don't know what to think.
