opinions would be nice..

me and my fiance have been ttc for 8 months now. Every month is the same , Af is always there on time .... this month Af was do on 9/21.. she still hasn't arrived ... I've had lower abdominal pains , very bad heart burn (which I hardly never have) , lower back pains , nausea , tiredness , sore breasts, very moody ( my fiance's opinion) , & a lot of headaches ... I was hopping for opinions on if I should test now or wait a little longer?
