The girl I like knows the truth please help me!?

Okay so, this girl I like is a sophmore and i am a junior in highschool. I told her i liked her fewdays ago, one on one, face to face. When I told her I liked her her reaction was kinda shy smiling and kinda awkward and kinda embarred....after i told her we pent the next half an hour talking, played piano and kinda flirting. and i walked her home. the awkwardness wore off few minutes after i told her i liked her. Last i walked her home. But! one thing. I forgot to ask her if she wanted to start a relationship with me. is it too late, or i still have time to make it up.? thank you for you guys help. i appreciate it.
