The increase in your Beta HCG level from 284 to 331.8 within a couple of days is generally considered normal during early pregnancy. Beta HCG levels usually double every two to three days in the first few weeks of pregnancy. However, it's important to note that individual experiences may vary. It's always best to consult with your healthcare provider who can assess your specific situation and provide appropriate guidance based on your medical history and any other relevant factors. They may recommend additional tests or monitoring to ensure the healthy progression of your pregnancy.
