Low hcg levels early pregnancy ! ? Anyone ?

[ShareLove]

Hey there , I am so worried ! I had 2 hcg tests done private ,
At 4+4 my hcg was 413
And then at 5+3 it was only 2900
So it hasn’t doubled …
It should have been around 3000ish shouldn’t it ?
If I go by 48 hours …
What’s the chance this pregnancy will fail ? Thank for any advice xx

I'm not a medical professional but I have read it needs to rise 53 percent every 48 hours minimum for a viable pregnancy. Obviously the higher the better, but it only needs to be 53 percent.
