[F]It has been 48 days since my last period(28 day cycle). I have taken numerous hpt's and had a blood test done at the hospital Sunday night that came back negative that night as well:( . I have had some nausea with this. I am not stressed out at all. I am 30 years old. How many women out there have gone through this and what was the outcome? I have taken more than one can imagine when it comes to hpt. But I know something is up.
