I went to my obgyn yesterday because of very sharp persistent pain on my right side. I am more than a week late for AF but all home tests have been negative. She said that she couldn't do a blood test to determine if I'm pregnant because a week after missed period is still too early for results on a blood test. I do feel like I could be pregnant and the sharp pain is making me very nervous. Is there another way I could get a blood test confirmation? Is it possible to be pregnant and still getting BFN on urine tests 8 days after missed AF?
