AF two days late..... Negative PT

Jemma

Hi everyone, i'm very new to this..

AF is now 2 days late, she should have arrived on Monday, I have a Mmc in August (my first pregnancy) and the last 2 cycles have been 28 days, I also have PCOS.

On Sunday I had cramping like AF was coming but still no sign, I seem to be getting a lot of saliva as well, I have done two hpt and got negative results .

Could it be false negative due to taking the hpt too early?

Any feedback would be great
