I feel like I should have a dark positive by now and I’m getting really concerned..I just had an ectopic in November so that’s why I’m so worried. I had blood work yesterday waiting to hear back, then repeat blood work Wednesday to make sure HCG is doubling. Does it matter how dark the line is?! These were all taken at the same time with first morning urine.
