Af started September 26th and lasted 3 days as usual. Had unprotected sex 2 nights in my most fertile days and then on the 12th of October I got what I think might be AF but that means she was 8 days early (25-26 days in cycle) but in the 13th of October I had brown spotting and when I wiped ? The 14th it went to pinkish spotting and was gone by that night? AF is due tomorrow but I have been getting negative results back every morning with FMU is there a chance I could be pregnant?

P.S I never get signs that AF is on the way and never get cramps during AF I just wake up and it's arrived with out knowing lol 😊
