Clearblue digital w/weeks indicator

Michelle? • I have a 3 year old son and just got my bfp for baby #2!!!❤️❤️❤️
Hi ladies, I took the clearblue digital test with weeks indicator and it said 1-2 weeks but according to last period I should be almost 6 weeks. I didn't use fmu, could this have affected the weeks? Or am I not as far as I think.
