Is there any hope?

This cycle has gone something like this

11 dpo - dark brown spotting

13 dpo - vfl on boots brand with fmu a bit more spotting but pink and a bit of red with ewcm?

Today 14 dpo and day of expected af. Haven’t started and still just a bit of brown but mostly clear ewcm. Tried a FRER at 6pm shown in pics

I have a three year old and a 19 month old and had very dark bfp by this stage with vfl at 9-10 dpo with both

I know all pregnancies can be different but maybe chemical or maybe not anything at all?
