I had my beta hCG done yesterday. It came as 2.00. I had sex recently. Eight months ago, when I had done the same test, my beta hCG was less than 0.1. Why this increase from 0.1 to 2? Is it because I can be pregnant and the hCG is increasing gradually? Or there are other reasons as well which increases it? I wanted to ask this because I am also experiencing early pregnancy symptoms like morning sickness, vomiting, a bit of back pain as well. My appetite is down.
