Any mamas with twins?

I'm super curious about the idea and would love if I had twins, so I'm just wondering, did you have any suspicion you were carrying twins or did you feel any different causing you to be suspicious? Also, when did you find out? I have yet to go to my first ultrasound. I won't have one until I'm going on 11 weeks. (Currently 8w2d)
I've heard mothers of twins sometimes have stronger symptoms but not sure how true this is. 😊
