Am i out?

So im around 9-10dpo and i did an hcg blood test bc i wanted to see what the result would be ,and it came back 1.47 - so negative…

Ive been feeling bloated, back pain and other symptoms. But it can also be period related. Supposed to get my period around the 20th.

I believe if the blood test came back that low, im not pregnant and should wait for aunt flow??
