She's still here

and no I didn't.
I'm 21dpo - usually have af at 13/15dpo so i'm way past usual.
I've had mixed tests both positive and negative.
But I have had a blighted ovum before (where the sac grows but it is empty - no baby in it).
And I fear this may be either a blighted ovum or a chemical pregnancy.
I'll go to cd 40 (about another 4 days) and if still nothing either way i'll see my doctor then.
