I came across a listing of how sensitive pregnancy tests are (not all tests are created equal). Sensitivity means how much HCG hormone do you need to produce to get a positive test.
It might be worth checking out. There are a tons of people that use "dollar store cheapies" while others swear by the First Response Early Result (my test of choice). First Response might be a little more sensitive but the dollar store tests seem to be at the top of the class. I was surprised to see that digitals aren't as sensitive. I figured since they were so much more money they would be better.
Peestickparadise.com has a list of people that reported when they got their BFP-so based on true accounts. The results show the First Response Early Result might not be as sensitive as we might think. It shows the earliest positive for FRER was 10dpo and all showed positives by 13dpo.
To me this proves that you can definitely get an early positive (before 14dpo), but is that best? What if it is a chemical pregnancy, is it better not to know?
