Twins ??

I’ve had constant dreams that I’m having twins and I’ve also been having round ligament pain and rib cage pain and I’m only 9 weeks?!? I heard that it can happen to short people early but I’m 5”8. It runs all throughout my family and my fiancé’s family. And my hcg was very high. I don’t know it’s just so strange that I’m having these pains so early and it’s already uncomfortable to lay on my stomach. What do y’all think?
