Spotting 14DPO??

I’m currently 14dpo today, I tested with FMU and got a negative with an internet cheapie. I went to the toilet now and had a tiny amount of pink spotting and creamy sticky cm. Af is due tomorrow so I’m not sure if it’s that or if it’s still possible to get a bfp at this stage? Has sore breaths for over a week already and bloating mostly in the evenings.
