AF was supposed to show up 2/16 but I still no sign of her. Having a lot of nausea, cramping/ abdominal pain, breast tenderness and very moody. I took a hpt yesterday morning but it was a bfn. Is is possible that my hcg levels were just not high enough and I need to wait alittle longer before testing again. I have been this way for 2 days and I am miserable. What do you all think?
