Why do people take multiple pregnancy tests?

I didn’t take a pregnancy test until I was 3-4 days overdue for my period. At that point 1 test and that was it.

I think it depends on the person, I took multiple in the first early days/week or so as I'd had early miscarriages and the darkening lines were a bit of comfort, showing my levels were still going up and not dropping.

Sometimes, people take the test too early for a line to show, so they would do it again.

In my 1st pregnancy, my period was 10 days late. I took a test around the 5th day but it was negative. Then I did one everyday after that which then showed positive on Day 10. That’s the reason I did multiple tests. Everyone is different though

In my 2nd pregnancy, I took only 1 test because I was nearly 3 months pregnant but had no symptoms. So there was no need to repeat as the line was extremely dark😂

Personally,
I went through infertility for around 3 years before falling pregnant with ICSI/IVF. It felt too good to be true and I tested constantly until my 8 week scan.

I was similar i took 1 test and it was too faint, I then got a digital test the next day and it was positive 🥹 I didnt take another one after that x
