Clear blue digital advice ladies

Martine

So I took a clear blue digital today as I was worrying about me getting enough Symptoms or if they were progressing.

So my first day of my last period was 14th June... and I’m 5 weeks On 19th july.

My digital test works it out from conception which states I’m 3 weeks+

Which would make me 5weeks+

I’m confused as should the test say I’m 2-3weeks which would make me 4-5 weeks?

Advice please ladies
