Beta results? 19.4

So I got my first very faint positive at 9dpo yesterday. Today my test were clearly 10dpo positive so I ran to the doctors for a beta check and progesterone check. I got my betas back and she said they were 19.45 where she said is fine because I’m very early. But after two losses my nerves are all over the place. I go back for a repeat on Thursday. But what are everyone’s input?
