Clear blue help? Surely not twins?

Hello!

I found out I was pregnant at 11 dpo. I had been temping and ovulation sticks so I know exactly timing wise when things happened.

I took a test on 1st aug and it came up 1-2 weeks which is great.

5 days later … 16dpo. It is now saying 3+ weeks

I was expecting 1-2 still or even 2-3. Which happened in my previous pregnancies.

There’s no way a clear blue can indicate twins right? I’m just so confused why the weeks have jumped up so quickly…

I tested at 5:30 too… so it is diluted !!

Any opinions would be great xx
