Did you know you had twins?

I'm just curious if anyone had a hunch they were having twins and did? I have been gaining weight like crazy and I'm 10 weeks but I look more like 16 weeks. It was very different with my first, and I know every pregnancy is different and you can show earlier with the second but this one feels super weird! I'm also been having twin dreams a lot. I know it's not for sure till I get my ultrasound but I still have 2 more weeks to see and I'm getting antsy 😁
