HCG levels question 💕

Hey, ladies! One of my best friends has struggled with getting pregnant for years. Unfortunately, she has had multiple miscarriages in the process. 😔

She recently found out she’s pregnant & her levels on Wednesday were a little over 1,100. Today, which is Friday, her levels are over 17,000! We all are so happy for her & she is over the moon! ♥️

Our question is, could this means multiples?

We know that the levels are supposed to double, but has anyone experienced such a huge jump & ended up with multiples?
