Hcg levels

I was 7 weeks on 11/11.

Hcg level on 11/12: 40,009

Hcg level on 11/16 (96 hours later): 61,372

After these levels, my physician thinks I’m maybe a week later than I originally thought, first ultrasound is on 11/27.

I know that weeks 0-5 they double every 24-48 hours, and 3-5+ days every week thereafter. My physician is not concerned at all! Just wondering, has anyone else tested later and had their levels rise “slower” and what was your outcome? No negative signs such as loss of symptoms, bleeding. Anxious first time mama here 💛
