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

Nicola • I`m a 32 year old teacher from the UK. Had my rainbow baby in September 2017 after miscarrying twice. Had a chemical pregnancy in January and now TTC #2
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. 
I'm very confused and need to know lol 🌸🐣😩
