Twins HCG levels

what were yalls betas and did it gave you any inclination it could be twins. my first beta at 3wks 6 days was 285, going for my second one on friday. i feel like it’s twins - which i never felt in my other pregnancies.

*i know hcg does not determine twins , only an ultrasound , but just wondering if there’s a pattern based off of what i’ve seen.
