Low beta hcg but doubling, what are my chances?

[Clove86]

So I just got my second beta results:
11dp5dt- 21.2
13dp5dt - 49.8

It has doubled but still extremely low. Also having brown spotting the last 24 hours. Does this seem like it will be viable? Please be honest, I’m prepared for the worst. Had a chemical before and beta never doubled like this, stayed at 30 then dropped. My tests still look like they’re progressing but I know the blood is more accurate. Third beta is in 2 days.

Hi @Clove86, sorry you are going through this. I have not experienced the same but didn't want to read and run. In my unsuccessful pregnancies my beta was always higher than yours but it was not doubling and i was told that the doubling was more important. True in my case (for 3 miscarriages)
Good luck, hope it's a positive outcome for you
