BFP or BFN? Help, I'm so confused.

I tested on Friday using a cheap strip test and got a faint BFP (top left picture). Then yesterday I did a first response and clearblue and they were both negative (bottom left). My AF was due yesterday and I started bleeding/spotting but it was brown. The bleeding stopped and I did another first response test this morning and got another faint positive (picture on right). I'm still bleeding a little bit but again it's brown and there isn't much.
