Period late but BFN....

Chelsey

Hi all! My period is now 5 days late and I keep getting negative pregnancy test results, 4 days ago when I went to the toilet and wiped there was a little bit of pink blood so I just presumed AF was here....but that's literally been it until yesterday I had the smallest dot of bright red blood (sorry TMI 🙈) my boobs have been extremely sore but once again I guessed it was down to AF.

I usually work like clock work and my period comes right on time every month....has anyone experienced this before??? Any advice would be appreciated! Thank you.
