I took a test this morning the day before af and it came back as a bfn😩 is it possible to then have a bfp tomorrow on the day af is due? I have had loads of symptoms such as cramps, pain in my right hand side, tired, feeling sick, feeling dizzy, constipation, change in my cm (very thick and white, lots of it) I just feel off and different to normal! Do you I still have a chance? Shall I test tomorrow morning or wait until Monday (5 days) to see if af arrives?
