I am currently pregnant with my third child or more ( I go to the doctor tomorrow ) but I have a huge gut feeling that I am having twins. I have put on about 15 pounds so far (estimated 12 weeks) and I'm already starting to show.
My grandfather was a twin and I have another set of twins in my family. Did you mommas know right away? Did you have a gut feeling?

Ditto.
Yup. I was completely floored when they told me.
Ultrasound.
We even did fertility treatments, so we knew our chances of multiples was greatly increased. Even then, I still dropped the 'F' bomb when we saw them on the screen.

GSx2 for T&B - EDD 6/21/2015 - They're having a GIRL!
ETA that if this is your 3rd pg, it doesn't seem unusual that you'd start showing early? Also, I only gained 6 pounds in the first tri, and that's because I ramped up my caloric intake when I found out it was twins. Congrats on your pregnancy either way!
CONGRATULATIONS
What did your ultrasound show?
