I’m currently experiencing the exact same thing ! Period was due last Friday and still nothing. I took a clearblue on Saturday which was negative but like you did it after a large glass of water and 2nd wee.
Same I was due on 11th still nothing had cramps on 10th but still absolutely no sign of af and 2 negatives. Today I did with fmu
@Sasha are you thinking of testing again?
If it doesn’t come by this Friday (a weeks late) I will test again
Just got my period today, 5 days late. Never been this late before, got my hopes up, so disappointed and sad
It is possible. Also I'd disregard instructions and do it with fmu anyway.
