Digital first responce test

Hi, so I’m 3 days late for my period and have no signs of it started.

I normally use the normal first response tests. But a digital one is all I had in right now so thought I would give it a try.

I’ve avoided them in the past as I’ve been told you need to have high hcg and perilously only picked up when I was 3-4 weeks after conception (as we did ivf)

I had a miscarriage in April so was putting off testing.

I tested and it’s negative.

So my question is what is your opinion of first responce digital test. ? Do I trust it or should I go get more.
