Pregnant? HELP?!

[RubysGold]

I bought my mare last week, and I dont know if she is pregnant or just a big build. When she walks towards me her tummy seems to swing from side to side? She also stares at me if i'm grooming, tacking up, but never shows 'mareish' behaviour
How do i tell?

Get your vet to scan her?

ditto above
the only possible of telling is getting her scanned
