How long does it take for 1-2 weeks to go up on a clearblue digital?

Question

I am 4 weeks pregnant and getting 1-2 at the moemnt, when will that go up to 2-3?

Answer

Just wanted to say those were recalled in the US because the weeks were so inaccurate and causing a lot of stress to mamas.  So don’t panic if it doesn’t increase as you expect it to xx
