9/10dpo is it normal

Iv had 3 positives that are faint but clearly there on easy @home strips. But I took one that’s really faint and another yesterday that basically looked negative. I only got the positives yesterday to.

So yesterday I had a pos, then a neg then tested again in evening with pos,

Then today (FMU) got a pos and then this evening a fainter line again.

Being im early in testing, is ot normal still find a fainter one or neg when clearly you have drank through day etc?
