AF due today 3/9 and was a no show!!!!!

Sara • Ttc #2 with my husband, we`ve been together for 10yrs, married 3 together have a beautiful one year old daughter.
So, AF was due today and is a no show!! I've been experiencing all day sickness w/o vomiting. Fatigue, tender breasts, dark veins on breasts and extreme constipation. I'm wanting to hold off on testing cause I'm afraid I'll be sad.. I do have a dr appt next week for my annual exam so I figured I'll just test then.. Fingers crossed ladies!!
