Weeks reducing on clearblue? Help!

Shannen

Hi I got 3+ weeks on Friday when I was 21dpo I got it in the evening , I tested with FMU that day and it was still 2-3. Anyway I had one left so I stupidly decided to do it a while ago I'm 23dpo today , my urine wasn't concentrated at all and only about an hour hold but 2-3 Weeks came up😟😫 I'm now worrying myself sick. I have an early scan on Thursday when I'll be 5+6. I've no bad signs only lower back pain but it's not even bad. Has this happened to anybody before and everything was 0k? Xx
