Pregnancy multiple question

An

I found out im Pregnant & go in for blood work in a week & a half. I'm curious for the mommies who have twins....did you have a feeling? were symptoms stronger? any type of signs? or can you only tell by an ultrasound? im probably 4 1/2/5 weeks if everything is correct and I just feel different than my first pregnancy. hard to explain but worth the ask 😁
