Early hCG Levels

Hi all! It’s my first pregnancy and I’m just anxious. I tested positive on 10 dpo. My hCG was 186 on 12 dpo and 286 on 14 dpo. I am soooo nervous because it didn’t double. I know the rule of thumb is no longer it must double in super early days, but did anyone have a similar experience (viable or nonviable pregnancy)?

I looked at Betabase and I’m in the average on both, I just was so hoping I’d be at like 400 or something after 48 hours…

I’m having my hCG retested tomorrow and should have more information.

Thank you!
