Don't waste your money on those, they might just cause you worry! I got a 1-2 at 10dpo and then a 2-3 at 15dpo. I tried for a 3+ at 21, 22, and 23 dpo and still got 2-3 and was freaking out. I went and got my beta drawn at 22dpo and my HCG was 7661! The stupid test is supposed to give you a 3+ at 2600. I think it's a rip off because they know women will keep buying tests to see the numbers go up and if they don't get the number they think they should have, they'll just keep testing. There's some other gals on here that have had the same experience. I started a thread about it in the First tri boards somewhere.
