If you received a positive on this test, did you get any positives on a "regular" test FIRST ?

I do know that digitals require more hCG to detect it, however, out of all the digital tests out there - I have read it is one of the most sensitive.

Please comment below!!!!! Thank u!!!!

<I'm asking as I am testing early and have experienced what I believe are indent lines on the first response tests but one of them had what looked like a vf positive for sure yesterday but retesting today with FMU I got another negative. I have one clear Blue digital with weeks test left and I'm wondering how early I can use it. Aunt flow is due on November 18 and per the instructions you can use that 5 to 6 days before expected period. I do not want to test too soon and ruin it-- I had a two pack and used one this morning but it was bfn>

Thanks!
