HCG levels

Larae

Could I be pregnant with twins?? So I went to the doctor for blood work Wednesday 3/3/21 and my HCG was 2,045 and I went back today 3/8/21 and my HCG is now 21,408 😱 In 5 days is this normal?? Sounds like some pretty high levels for only 5 weeks...please share your thoughts especially if your having twins 👯‍♀️
