OK, so I have just gone to the toilet again and wiped and there was nothing there. I think I will do a test tomorrow morning with FMU and see what happens.

Ryn, I think I will test again on Mon / Tues like you suggested if I dont get bright red blood and if tomorrows test is a negative. Is it better to test with a HPT that\is 10Miu or 20MIu - whats the most sensitive?
