@jerryjrmommy, Im thinking about holding it off until this week is over and if i still get a negative test and no period I will have to go to my obgyn. When I was pregnant with my first I got a negative blood test! So I took a test a week after I had that test done and I got a positive so I went back for a blood test and It came back positive that time. My last period was jan 8. I have my cycle every 28 days and Im very regular.
