Twins?

AutumnleeRose
I had my first doctors appt today, I'm 14 weeks + 1 day & my midwife thinks I'm having twins. Twins do not run in my family or my so's. She says that I am larger then normal, by 4 weeks or so. I know I have my LMP dates correct & everything! I am freaking out!! When was the earliest the doctor could tell its twins? & has anyone found out they were having twins by just a check up without ultrasound, & having the ultrasound tech confirm it? Wondering if anyone went through this as well.
FYI, we got pregnant naturally (& fast!!)
Thanks for giving it a read 😊
