Are these tests really that accurate?? I'm 5 weeks today and mine is still reading 1-2 weeks (which means I'm 3-4 weeks along). It hasn't moved up to 2-3, and should be saying 3+ now! But all of my line tests have gotten super dark daily! Do obviously my hcg hormone is going up. Why isn't clearblue reading accurate then?? I'm so worried about another mc :(
