I'm going to wait till Sunday when it officially hits a week late and take another test, if that comes up negative I was going to make an appointment with my obgyn and see if maybe the hormones aren't high enough yet to be detected
So, here is my experience:
My first month TTC my period was a week late. I was sure I was pregnant because I haven't been late since I was 13! Even thought the HPT's were negative, I knew I was pregnant.
Well, about a week late, af showed.
I'm pretty sure that I was so nervous/excited/stressed about finally TTC that it messed up my cycle.
P.S. Preggo is a spaghetti sauce.
