With clear blue digital, take 4 weeks + the conceived weeks, so you're probably around 6-7 weeks or a week earlier. Google about clear blue digital and you'll get what I mean.
Your LMP might be inaccurate too. I missed my period for 2 weeks also then used the clear blue and it stated 1-2 weeks pregnant. After calculations based on my lmp which of course is not accurate, I estimated myself to be about 5-6 weeks pregnant. Got my 1st appointment 4 weeks later and estimated I should be around 11 weeks but based on ultrasound I was 10 weeks 2 days. Can see my fetus and hear it's heartbeat already. So you can start to book an appointment already.
