Could I be having another chemical pregnancy?

Vicky
Hi girls, more or less been in tears all morning. Found out last December I was pregnant that ended in a chemical pregnancy. Been tracking this month and got a bfp at 10dpo which was Friday... Went to the toilet today and I have browny pinky discharge and would be due on my period tomorrow so done a test just now and it's more or less the same colour as last nights one. Any advice or help would be lovely I'm just gutted right now at the thought of another chemical pregnancy. 
From the top first one is 10dpo 
Second and third is 11dpo 
Fourth last night at 12dpo
Last one at 13dpo which is todays
