Eye contact thingy, woul you help?

So i was in the entrance of the clroom today and i see this girl coming which looks at me, i notice she doing that and look into her eyes as well, she looks away. I look away and then our eyes meet again for like 3 or 4 seconds... and then she came close to me like 2metres away. Should i go talk to her next time i see her? Could it be she found me attractive or interested at least?
