So I wanted to share my experience so far, I started testing at 9dpo and got a faint on a FRER which is sensitive to around 6.5 miu of HCG. I was also testing with digitals and Assured (dollar store) brand and getting negatives on those. I found out from my doctor and google today that the dollar store tests needs 25 miu of HCG. So on 10dpo I got a very very very faint line on an Assured and a darker line on a FRER (good news)!! On the third day (today) at 11dpo I got an even darker line on an Assured and a darker line on FRER but still negatives on a digital which require 50 miu! So for all of you stressing like me about digitals I suggest using Assured first then once you get a dark line on those you can take a digital. And regardless of that you are only spending 1$ per test. I was so relieved to see the progressing lines on the Assured.

Here are comparison photos (and I got the DPOs wrong when I wrote them on the tests so they are one day ahead)

Both are 11 DPO (first picture)

Top one is 10 DPO bottom 11 DPO (second picture)
