Just wondering what your earliest signs of twins were. Did you know you were having twins before you *actually knew*?

I'm hoping for twins, as they run in my family on both sides. My grandmother on my father's side was a twin, and my aunt on my mother's side has twins, as well as a set of cousins on that side that are twins.

Also, my hubby is a twin and so is is father, although I know that's not a factor.

I'm almost 6 weeks, and EXHAUSTED. Boobs are so sore I think they may explode. I feel a fullness in my pelvis, more so than in my pregnancy, although I'm overweight so not showing yet. I don't get to hear the heartbeat until Feb 21 so maybe I'm just overrunning/wishing too hard?

What do you guys think?
